16 tim 2807 is nowadays feasible using simple and efficient computer programs,
17     the calculation of such properties and, in general, the dynamic
18     behavior of flexible macromolecules has not reached a similar situation.
19     Although the theories are available, usually the computational work
20     is done using solutions specific for each problem. We intend to
21     develop computer programs that would greatly facilitate the task
22     of predicting solution behavior of flexible macromolecules. In this
23     paper, we first present an overview of the two approaches that are
24     most practical: the Monte Carlo rigid-body treatment, and the Brownian
25     dynamics simulation technique. The Monte Carlo procedure is based
26     on the calculation of properties for instantaneous conformations
27     of the macromolecule that are regarded as if they were instantaneously
28     rigid. We describe how a Monte Carlo program can be interfaced to
29     the programs in the HYDRO suite for rigid particles, and provide
30     an example of such calculation, for a hypothetical particle: a protein
31     with two domains connected by a flexible linker. We also describe
32     briefly the essentials of Brownian dynamics, and propose a general
33     mechanical model that includes several kinds of intramolecular interactions,
34     such as bending, internal rotation, excluded volume effects, etc.
35     We provide an example of the application of this methodology to
36     the dynamics of a semiflexible, wormlike DNA.},

52     abstract = {Time series analysis tools are employed on the principal modes obtained
53 tim 2807 from the C-alpha trajectories from two independent molecular-dynamics
54     simulations of alpha-amylase inhibitor (tendamistat). Fluctuations
55     inside an energy minimum (intraminimum motions), transitions between
56     minima (interminimum motions), and relaxations in different hierarchical
57     energy levels are investigated and compared with those encountered
58     in vacuum by using different sampling window sizes and intervals.
59     The low-frequency low-indexed mode relationship, established in
60     vacuum, is also encountered in water, which shows the reliability
61     of the important dynamics information offered by principal components
62     analysis in water. It has been shown that examining a short data
63     collection period (100 ps) may result in a high population of overdamped
64     modes, while some of the low-frequency oscillations (< 10 cm(-1))
65     can be captured in water by using a longer data collection period
66     (1200 ps). Simultaneous analysis of short and long sampling window
67     sizes gives the following picture of the effect of water on protein
68     dynamics. Water makes the protein lose its memory: future conformations
69     are less dependent on previous conformations due to the lowering
70     of energy barriers in hierarchical levels of the energy landscape.
71     In short-time dynamics (< 10 ps), damping factors extracted from
72     time series model parameters are lowered. For tendamistat, the friction
73     coefficient in the Langevin equation is found to be around 40-60
74     cm(-1) for the low-indexed modes, compatible with literature. The
75     fact that water has increased the friction and that on the other
76     hand has lubrication effect at first sight contradicts. However,
77     this comes about because water enhances the transitions between
78     minima and forces the protein to reduce its already inherent inability
79     to maintain oscillations observed in vacuum. Some of the frequencies
80     lower than 10 cm(-1) are found to be overdamped, while those higher
81     than 20 cm(-1) are slightly increased. As for the long-time dynamics
82     in water, it is found that random-walk motion is maintained for
83     approximately 200 ps (about five times of that in vacuum) in the
84     low-indexed modes, showing the lowering of energy barriers between
85     the higher-level minima.},

163     diliganded AChR gating appears to be a simple, two-state reaction.
164     However, mutagenesis studies indicate that during gating dozens
165     of residues across the protein move asynchronously and are organized
166     into rigid body gating domains (#blocks#). Moreover, there is an
167     upper limit to the apparent channel opening rate constant. These
168     observations suggest that the gating reaction has a broad, corrugated
169     transition state region, with the maximum opening rate reflecting,
170     in part, the mean first-passage time across this ensemble. Simulations
171     reveal that a flat, isotropic energy profile for the transition
172     state can account for many of the essential features of AChR gating.
173     With this mechanism, concerted, local structural transitions that
174     occur on the broad transition state ensemble give rise to fractional

589     ends at an angle 180 degrees - gamma. For L/D = 2 and gamma = 0,10,20
590     degrees, the simulations show isotropic, nematic, smectic, and solid
591     phases. For L/D = 2 and gamma = 30 degrees, only isotropic, nematic,
592     and solid phases are in evidence, which suggests that there is a
593     nematic-smectic-solid triple point at an angle in the range 20 degrees
594     < gamma < 30 degrees. In all of the orientationally ordered fluid
595     phases the order is purely uniaxial. For gamma = 10 degrees and
596     20 degrees, at the studied densities, the solid is also uniaxially
597     ordered, whilst for gamma = 30 degrees the solid layers are biaxially
598     ordered. For L/D = 2 and gamma = 60 degrees and 90 degrees we find
599     no spontaneous orientational ordering. This is shown to be due to
600     the interlocking of dimer pairs which precludes alignment. We find
601     similar results for L/D = 9.5 and gamma = 72 degrees, where an isotropic-biaxial
602     nematic transition is predicted by Onsager theory. Simulations in
603     the biaxial nematic phase show it to be at least mechanically stable
604     with respect to the isotropic phase, however. We have compared the
605     quasi-exact simulation results in the isotropic phase with the predicted
606     equations of state from three theories: the virial expansion containing
607     the second and third virial coefficients; the Parsons-Lee equation
608     of state; an application of Wertheim's theory of associating fluids
609     in the limit of infinite attractive association energy. For all
610     of the molecule elongations and geometries we have simulated, the
611     Wertheim theory proved to be the most accurate. Interestingly, the
612     isotropic equation of state is virtually independent of the dimer
613     bond angle-a feature that is also reflected in the lack of variation
614     with angle of the calculated second and third virial coefficients.

813     the fundamental cause of these instabilities. In this work, we trace
814     the instability to the nonanalytic character of the underlying spectrum
815     and show that a correct splitting of the Hamiltonian, which renders
816     the spectrum analytic, restores stability. The resulting Hamiltonian
817     dictates that in addition to updating the momentum due to the slowly
818     changing force, one must also update the position with a modified
819     mass. Thus multiple-time stepping must be done dynamically. (C)

1302 tim 2807 with an application to bovine pancreatic trypsin inhibitor (BPTI),
1303     is reported. The unfolding and refolding of the native structure
1304     of the protein are characterized by the dimensions of the protein,
1305     expressed in terms of the three principal radii of the structure
1306     considered as an ellipsoid. A dynamic equation, describing the variations
1307     of the principal radii on the unfolding path, and a numerical procedure
1308     to solve this equation are proposed. Expanded and distorted conformations
1309     are refolded to the native structure by a dimensional-constraint
1310     energy minimization procedure. A unique and reproducible unfolding
1311     pathway for an intermediate of BPTI lacking the [30,51] disulfide
1312     bond is obtained. The resulting unfolded conformations are extended;
1313     they contain near-native local structure, but their longest principal
1314     radii are more than 2.5 times greater than that of the native structure.
1315     The most interesting finding is that the majority of expanded conformations,
1316     generated under various conditions, can be refolded closely to the
1317     native structure, as measured by the correct overall chain fold,
1318     by the rms deviations from the native structure of only 1.9-3.1
1319     angstrom, and by the energy differences of about 10 kcal/mol from
1320     the native structure. Introduction of the [30,51] disulfide bond
1321     at this stage, followed by minimization, improves the closeness
1322     of the refolded structures to the native structure, reducing the
1323     rms deviations to 0.9-2.0 angstrom. The unique refolding of these
1324     expanded structures over such a large conformational space implies
1325     that the folding is strongly dictated by the interactions in the
1326     amino acid sequence of BPTI. The simulations indicate that, under
1327     conditions that favor a compact structure as mimicked by the volume
1328     constraints in our algorithm; the expanded conformations have a
1329     strong tendency to move toward the native structure; therefore,
1330     they probably would be favorable folding intermediates. The results
1331     presented here support a general model for protein folding, i.e.,
1332     progressive formation of partially folded structural units, followed
1333     by collapse to the compact native structure. The general applicability

1351 tim 2807 described by diffusion in a strongly anharmonic potential. In this
1352     paper, we try to understand the form and origin of the anharmonicities,
1353     with the principal aim of gaining a better understanding of the
1354     principal motion types, but also in order to develop more efficient
1355     numerical methods for simulating neutron scattering spectra of large
1356     proteins. First, we decompose a molecular dynamics (MD) trajectory
1357     of 1.5 ns for a C-phycocyanin dimer surrounded by a layer of water
1358     into three contributions that we expect to be independent: the global
1359     motion of the residues, the rigid-body motion of the sidechains
1360     relative to the backbone, and the internal deformations of the sidechains.
1361     We show that they are indeed almost independent by verifying the
1362     factorization of the incoherent intermediate scattering function.
1363     Then, we show that the global residue motions, which include all
1364     large-scale backbone motions, can be reproduced by a simple harmonic
1365     model which contains two contributions: a short-time vibrational
1366     term, described by a standard normal mode calculation in a local
1367     minimum, and a long-time diffusive term, described by Brownian motion
1368     in an effective harmonic potential. The potential and the friction
1369     constants were fitted to the MD data. The major anharmonic contribution
1370     to the incoherent intermediate scattering function comes from the
1371     rigid-body diffusion of the sidechains. This model can be used to
1372     calculate scattering functions for large proteins and for long-time
1373     scales very efficiently, and thus provides a useful complement to
1374     MD simulations, which are best suited for detailed studies on smaller

1394     first approach exploited the fact that the presence of water in
1395     the excited state solvent cage of a fluorophore increases the rate
1396     of decay. For 1,6-diphenyl-1,3,5-hexatriene (DPH) and 1-palmitoyl-2-[[2-[4-(6-phenyl-trans-1,3,5-hexatrienyl)
1397     phenyl]ethyl]carbonyl]-3-sn-PC (DPH-PC), where the fluorophores
1398     are located in the hydrophobic core of the lipid bilayer, the introduction
1399     of gramicidin reduced the fluorescence lifetime, indicative of an
1400     increased presence of water in the bilayer. Since a high protein:lipid
1401     ratio was used, the fluorophores were forced to be adjacent to the
1402     protein hydrophobic surface, hence the presence of water in this
1403     region could be inferred. Cholesterol is known to reduce the water
1404     content of lipid bilayers and this effect was maintained at the
1405     protein-lipid interface with both gramicidin and apocytochrome C,
1406     again suggesting hydration in this region. The second approach was
1407     to use the fluorescence enhancement induced by exchanging deuterium
1408     oxide (D2O) for H2O. Both the fluorescence intensities of trimethylammonium-DPH,
1409     located in the lipid head group region, and of the gramicidin intrinsic
1410     tryptophans were greater in a D2O buffer compared with H2O, showing
1411     that the fluorophores were exposed to water in the bilayer at the
1412     protein-lipid interface. In the presence of cholesterol the fluorescence
1413     intensity ratio of D2O to H2O decreased, indicating a removal of
1414     water by the cholesterol, in keeping with the lifetime data. Altered
1415     hydration at the protein-lipid interface could affect conformation,

1521     obtained for damping coefficients that are only a few percent of
1522     the natural decay rate of processes of interest, such as the velocity
1523     autocorrelation function. Two new multiple time stepping integrators,
1524     Langevin Molly (LM) and Brunger-Brooks-Karplus-Molly (BBK-M), are
1525     introduced in this paper. Both use the mollified impulse method
1526     for the Newtonian term. LM uses a discretization of the Langevin
1527     equation that is exact for the constant force, and BBK-M uses the
1528     popular Brunger-Brooks-Karplus integrator (BBK). These integrators,
1529     along with an extrapolative method called LN, are evaluated across
1530     a wide range of damping coefficient values. When large damping coefficients
1531     are used, as one would for the implicit modeling of solvent molecules,
1532     the method LN is superior, with LM closely following. However, with
1533     mild damping of 0.2 ps(-1), LM produces the best results, allowing
1534     long time steps of 14 fs in simulations containing explicitly modeled
1535     flexible water. With BBK-M and the same damping coefficient, time
1536     steps of 12 fs are possible for the same system. Similar results
1537     are obtained for a solvated protein-DNA simulation of estrogen receptor
1538     ER with estrogen response element ERE. A parallel version of BBK-M
1539     runs nearly three times faster than the Verlet-I/r-RESPA (reversible
1540     reference system propagator algorithm) when using the largest stable
1541     time step on each one, and it also parallelizes well. The computation

1868     membrane, we performed molecular dynamics simulations on a phospholipid
1869     (DPPC)/water system with atomic detail. Since the actual process
1870     of permeation is too slow to be studied directly, we deduced the
1871     permeation rate indirectly via computation of the free energy and
1872     diffusion rate profiles of a water molecule across the bilayer.
1873     We conclude that the permeation of water through a lipid membrane
1874     cannot be described adequately by a simple homogeneous solubility-diffusion
1875     model. Both the excess free energy and the diffusion rate strongly
1876     depend on the position in the membrane, as a result from the inhomogeneous
1877     nature of the membrane. The calculated excess free energy profile
1878     has a shallow slope and a maximum height of 26 kJ/mol. The diffusion
1879     rate is highest in the middle of the membrane where the lipid density
1880     is low. In the interfacial region almost all water molecules are
1881     bound by the lipid headgroups, and the diffusion turns out to be
1882     1 order of magnitude smaller. The total transport process is essentially
1883     determined by the free energy barrier. The rate-limiting step is
1884     the permeation through the dense part of the lipid tails, where
1885     the resistance is highest. We found a permeation rate of 7(+/-3)
1886     x 10(-2) cm/s at 350 K, comparable to experimental values for DPPC
1887     membranes, if corrected for the temperature of the simulation. Taking
1888     the inhomogeneity of the membrane into account, we define a new

2165     stress is increasingly partitioned to writhe. The magnitude of writhe
2166     surpasses that of twist before also leveling off when the structure

2448     increased flexibility, better error handling, and ease of debugging.
2449     We introduce ANTLR, a public-domain parser generator that combines
2450     the flexibility of hand-coded parsing with the convenience of a
2451     parser generator, which is a component of PCCTS. ANTLR has many
2452     features that make it easier to use than other language tools. Most
2453     important, ANTLR provides predicates which let the programmer systematically
2454     direct the parse via arbitrary expressions using semantic and syntactic
2455     context; in practice, the use of predicates eliminates the need
2456     to hand-tweak the ANTLR output, even for difficult parsing problems.
2457     ANTLR also integrates the description of lexical and syntactic analysis,
2458     accepts LL(k) grammars for k > 1 with extended BNF notation, and
2459     can automatically generate abstract syntax trees. ANTLR is widely
2460     used, with over 1000 registered industrial and academic users in
2461     37 countries. It has been ported to many popular systems such as
2462     the PC, Macintosh, and a variety of UNIX platforms; a commercial

2723     channel. Because of the different dynamical regimes for the three
2724     species (high barrier for Na+, low barrier for K+, almost free diffusion
2725     for water), different methods are used to calculate the mobilities.
2726     By use of activated dynamics and a potential of mean force determined
2727     previously (Roux, B.; Karplus, M. Biophys. J. 1991, 59, 961), the
2728     barrier crossing rate of Na+ ion is determined. The motion of Na+
2729     at the transition state is controlled by local interactions and
2730     collisions with the neighboring carbonyls and the two nearest water
2731     molecules. There are significant deviations from transition-state
2732     theory; the transmission coefficient is equal to 0.11. The water
2733     and K+ motions are found to be well described by a diffusive model;
2734     the motion of K+ appears to be controlled by the diffusion of water.
2735     The time-dependent friction functions of Na+ and K+ ions in the
2736     periodic beta-helix are calculated and analyzed by using a generalized
2737     Langevin equation approach. Both Na+ and K+ suffer many rapid collisions,
2738     and their dynamics is overdamped and noninertial. Thus, the selectivity

2824     abstract = {Numerical resonance artifacts have become recognized recently as a
2825 tim 2807 limiting factor to increasing the timestep in multiple-timestep
2826     (MTS) biomolecular dynamics simulations. At certain timesteps correlated
2827     to internal motions (e.g., 5 fs, around half the period of the fastest
2828     bond stretch, T-min), visible inaccuracies or instabilities can
2829     occur. Impulse-MTS schemes are vulnerable to these resonance errors
2830     since large energy pulses are introduced to the governing dynamics
2831     equations when the slow forces are evaluated. We recently showed
2832     that such resonance artifacts can be masked significantly by applying
2833     extrapolative splitting to stochastic dynamics. Theoretical and
2834     numerical analyses of force-splitting integrators based on the Verlet
2835     discretization are reported here for linear models to explain these
2836     observations and to suggest how to construct effective integrators
2837     for biomolecular dynamics that balance stability with accuracy.
2838     Analyses for Newtonian dynamics demonstrate the severe resonance
2839     patterns of the Impulse splitting, with this severity worsening
2840     with the outer timestep. Delta t: Constant Extrapolation is generally
2841     unstable, but the disturbances do not grow with Delta t. Thus. the
2842     stochastic extrapolative combination can counteract generic instabilities
2843     and largely alleviate resonances with a sufficiently strong Langevin
2844     heat-bath coupling (gamma), estimates for which are derived here
2845     based on the fastest and slowest motion periods. These resonance
2846     results generally hold for nonlinear test systems: a water tetramer
2847     and solvated protein. Proposed related approaches such as Extrapolation/Correction
2848     and Midpoint Extrapolation work better than Constant Extrapolation
2849     only for timesteps less than T-min/2. An effective extrapolative
2850     stochastic approach for biomolecules that balances long-timestep
2851     stability with good accuracy for the fast subsystem is then applied
2852     to a biomolecule using a three-class partitioning: the medium forces
2853     are treated by Midpoint Extrapolation via position Verlet, and the
2854     slow forces are incorporated by Constant Extrapolation. The resulting
2855     algorithm (LN) performs well on a solvated protein system in terms
2856     of thermodynamic properties and yields an order of magnitude speedup
2857     with respect to single-timestep Langevin trajectories. Computed
2858     spectral density functions also show how the Newtonian modes can
2859     be approximated by using a small gamma in the range Of 5-20 ps(-1).

3150     all of the advantages of previous RESPA integrators but are reversible,
3151     and more stable than those methods. These methods are applied to
3152     a set of paradigmatic systems and are shown to be superior to earlier
3153     methods. It is shown how the new RESPA methods are related to predictor-corrector
3154     integrators. Finally, we show how these methods can be used to accelerate
3155     the integration of the equations of motion of systems with Nose

3200 tim 2807 liquid crystalline phases are studied by means of constant NPT Monte
3201     Carlo simulation methods. The popular Gay-Berne model mesogen is
3202     used as the reference fluid, which displays the phase sequences
3203     isotropic-smectic A-smectic B and isotropic-smectic B at high (T*=2.0)
3204     and low (T*=1.5) temperatures, respectively. With increasing quadrupole
3205     magnitude the smectic phases are observed to be stabilized with
3206     respect to the isotropic liquid, while the smectic B is destabilized
3207     with respect to the smectic A. At the lower temperature, a sufficiently
3208     large quadrupole magnitude results in the injection of the smectic
3209     A phase into the phase sequence and the replacement of the smectic
3210     B phase by the tilted smectic J phase. The nematic phase is also
3211     injected into the phase sequence at both temperatures considered,
3212     and ultimately for sufficiently large quadrupole magnitudes no coherent
3213     layered structures were observed. The stabilization of the smectic
3214     A phase supports the commonly held belief that, while the inclusion
3215     of polar groups is not a prerequisite for the formation of the smectic
3216     A phase, quadrupolar interactions help to increase the temperature
3217     and pressure range for which the smectic A phase is observed. The
3218     quality of the layered structure is worsened with increasing quadrupole
3219     magnitude. This behavior, along with the injection of the nematic
3220     phase into the phase sequence, indicate that the general tendency
3221     of the quadrupolar interactions is to destabilize the layered structure.
3222     A pressure dependence upon the smectic layer spacing is observed.
3223     This behavior is in much closer agreement with experimental findings
3224     than has been observed previously for nonpolar Gay-Berne and hard
3225     spherocylinder models. (C) 2003 American Institute of Physics.},

3241     abstract = {Based on a recent result showing that the net Coulomb potential in
3242 tim 2807 condensed ionic systems is rather short ranged, an exact and physically
3243     transparent method permitting the evaluation of the Coulomb potential
3244     by direct summation over the r(-1) Coulomb pair potential is presented.
3245     The key observation is that the problems encountered in determining
3246     the Coulomb energy by pairwise, spherically truncated r(-1) summation
3247     are a direct consequence of the fact that the system summed over
3248     is practically never neutral. A simple method is developed that
3249     achieves charge neutralization wherever the r(-1) pair potential
3250     is truncated. This enables the extraction of the Coulomb energy,
3251     forces, and stresses from a spherically truncated, usually charged
3252     environment in a manner that is independent of the grouping of the
3253     pair terms. The close connection of our approach with the Ewald
3254     method is demonstrated and exploited, providing an efficient method
3255     for the simulation of even highly disordered ionic systems by direct,
3256     pairwise r(-1) summation with spherical truncation at rather short
3257     range, i.e., a method which fully exploits the short-ranged nature
3258     of the interactions in ionic systems. The method is validated by
3259     simulations of crystals, liquids, and interfacial systems, such
3260     as free surfaces and grain boundaries. (C) 1999 American Institute
