16 tim 2797 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 2797 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.},

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

572     degrees, the simulations show isotropic, nematic, smectic, and solid
573     phases. For L/D = 2 and gamma = 30 degrees, only isotropic, nematic,
574     and solid phases are in evidence, which suggests that there is a
575     nematic-smectic-solid triple point at an angle in the range 20 degrees
576     < gamma < 30 degrees. In all of the orientationally ordered fluid
577     phases the order is purely uniaxial. For gamma = 10 degrees and
578     20 degrees, at the studied densities, the solid is also uniaxially
579     ordered, whilst for gamma = 30 degrees the solid layers are biaxially
580     ordered. For L/D = 2 and gamma = 60 degrees and 90 degrees we find
581     no spontaneous orientational ordering. This is shown to be due to
582     the interlocking of dimer pairs which precludes alignment. We find
583     similar results for L/D = 9.5 and gamma = 72 degrees, where an isotropic-biaxial
584     nematic transition is predicted by Onsager theory. Simulations in
585     the biaxial nematic phase show it to be at least mechanically stable
586     with respect to the isotropic phase, however. We have compared the
587     quasi-exact simulation results in the isotropic phase with the predicted
588     equations of state from three theories: the virial expansion containing
589     the second and third virial coefficients; the Parsons-Lee equation
590     of state; an application of Wertheim's theory of associating fluids
591     in the limit of infinite attractive association energy. For all
592     of the molecule elongations and geometries we have simulated, the
593     Wertheim theory proved to be the most accurate. Interestingly, the
594     isotropic equation of state is virtually independent of the dimer
595     bond angle-a feature that is also reflected in the lack of variation
596     with angle of the calculated second and third virial coefficients.

1253     abstract = {A new procedure for studying the folding and unfolding of proteins,
1254 tim 2797 with an application to bovine pancreatic trypsin inhibitor (BPTI),
1255     is reported. The unfolding and refolding of the native structure
1256     of the protein are characterized by the dimensions of the protein,
1257     expressed in terms of the three principal radii of the structure
1258     considered as an ellipsoid. A dynamic equation, describing the variations
1259     of the principal radii on the unfolding path, and a numerical procedure
1260     to solve this equation are proposed. Expanded and distorted conformations
1261     are refolded to the native structure by a dimensional-constraint
1262     energy minimization procedure. A unique and reproducible unfolding
1263     pathway for an intermediate of BPTI lacking the [30,51] disulfide
1264     bond is obtained. The resulting unfolded conformations are extended;
1265     they contain near-native local structure, but their longest principal
1266     radii are more than 2.5 times greater than that of the native structure.
1267     The most interesting finding is that the majority of expanded conformations,
1268     generated under various conditions, can be refolded closely to the
1269     native structure, as measured by the correct overall chain fold,
1270     by the rms deviations from the native structure of only 1.9-3.1
1271     angstrom, and by the energy differences of about 10 kcal/mol from
1272     the native structure. Introduction of the [30,51] disulfide bond
1273     at this stage, followed by minimization, improves the closeness
1274     of the refolded structures to the native structure, reducing the
1275     rms deviations to 0.9-2.0 angstrom. The unique refolding of these
1276     expanded structures over such a large conformational space implies
1277     that the folding is strongly dictated by the interactions in the
1278     amino acid sequence of BPTI. The simulations indicate that, under
1279     conditions that favor a compact structure as mimicked by the volume
1280     constraints in our algorithm; the expanded conformations have a
1281     strong tendency to move toward the native structure; therefore,
1282     they probably would be favorable folding intermediates. The results
1283     presented here support a general model for protein folding, i.e.,
1284     progressive formation of partially folded structural units, followed
1285     by collapse to the compact native structure. The general applicability
1286     of the procedure is also discussed.},

1303 tim 2797 described by diffusion in a strongly anharmonic potential. In this
1304     paper, we try to understand the form and origin of the anharmonicities,
1305     with the principal aim of gaining a better understanding of the
1306     principal motion types, but also in order to develop more efficient
1307     numerical methods for simulating neutron scattering spectra of large
1308     proteins. First, we decompose a molecular dynamics (MD) trajectory
1309     of 1.5 ns for a C-phycocyanin dimer surrounded by a layer of water
1310     into three contributions that we expect to be independent: the global
1311     motion of the residues, the rigid-body motion of the sidechains
1312     relative to the backbone, and the internal deformations of the sidechains.
1313     We show that they are indeed almost independent by verifying the
1314     factorization of the incoherent intermediate scattering function.
1315     Then, we show that the global residue motions, which include all
1316     large-scale backbone motions, can be reproduced by a simple harmonic
1317     model which contains two contributions: a short-time vibrational
1318     term, described by a standard normal mode calculation in a local
1319     minimum, and a long-time diffusive term, described by Brownian motion
1320     in an effective harmonic potential. The potential and the friction
1321     constants were fitted to the MD data. The major anharmonic contribution
1322     to the incoherent intermediate scattering function comes from the
1323     rigid-body diffusion of the sidechains. This model can be used to
1324     calculate scattering functions for large proteins and for long-time
1325     scales very efficiently, and thus provides a useful complement to
1326     MD simulations, which are best suited for detailed studies on smaller

1346     first approach exploited the fact that the presence of water in
1347     the excited state solvent cage of a fluorophore increases the rate
1348     of decay. For 1,6-diphenyl-1,3,5-hexatriene (DPH) and 1-palmitoyl-2-[[2-[4-(6-phenyl-trans-1,3,5-hexatrienyl)
1349     phenyl]ethyl]carbonyl]-3-sn-PC (DPH-PC), where the fluorophores
1350     are located in the hydrophobic core of the lipid bilayer, the introduction
1351     of gramicidin reduced the fluorescence lifetime, indicative of an
1352     increased presence of water in the bilayer. Since a high protein:lipid
1353     ratio was used, the fluorophores were forced to be adjacent to the
1354     protein hydrophobic surface, hence the presence of water in this
1355     region could be inferred. Cholesterol is known to reduce the water
1356     content of lipid bilayers and this effect was maintained at the
1357     protein-lipid interface with both gramicidin and apocytochrome C,
1358     again suggesting hydration in this region. The second approach was
1359     to use the fluorescence enhancement induced by exchanging deuterium
1360     oxide (D2O) for H2O. Both the fluorescence intensities of trimethylammonium-DPH,
1361     located in the lipid head group region, and of the gramicidin intrinsic
1362     tryptophans were greater in a D2O buffer compared with H2O, showing
1363     that the fluorophores were exposed to water in the bilayer at the
1364     protein-lipid interface. In the presence of cholesterol the fluorescence
1365     intensity ratio of D2O to H2O decreased, indicating a removal of
1366     water by the cholesterol, in keeping with the lifetime data. Altered

1419     dynamics. More specifically, stable and accurate integrations are
1420     obtained for damping coefficients that are only a few percent of
1421     the natural decay rate of processes of interest, such as the velocity
1422     autocorrelation function. Two new multiple time stepping integrators,
1423     Langevin Molly (LM) and Brunger-Brooks-Karplus-Molly (BBK-M), are
1424     introduced in this paper. Both use the mollified impulse method
1425     for the Newtonian term. LM uses a discretization of the Langevin
1426     equation that is exact for the constant force, and BBK-M uses the
1427     popular Brunger-Brooks-Karplus integrator (BBK). These integrators,
1428     along with an extrapolative method called LN, are evaluated across
1429     a wide range of damping coefficient values. When large damping coefficients
1430     are used, as one would for the implicit modeling of solvent molecules,
1431     the method LN is superior, with LM closely following. However, with
1432     mild damping of 0.2 ps(-1), LM produces the best results, allowing
1433     long time steps of 14 fs in simulations containing explicitly modeled
1434     flexible water. With BBK-M and the same damping coefficient, time
1435     steps of 12 fs are possible for the same system. Similar results
1436     are obtained for a solvated protein-DNA simulation of estrogen receptor
1437     ER with estrogen response element ERE. A parallel version of BBK-M
1438     runs nearly three times faster than the Verlet-I/r-RESPA (reversible
1439     reference system propagator algorithm) when using the largest stable
1440     time step on each one, and it also parallelizes well. The computation
1441     of diffusion coefficients for flexible water and ER/ERE shows that
1442     when mild damping of up to 0.2 ps-1 is used the dynamics are not

1770     structures as well as their preservation along solutions can be

1772     we prove that a unique multisymplectic structure is obtained by
1773     taking the derivative of an action function, and use this structure
1774     to prove covariant generalizations of conservation of symplecticity
1775     and Noether's theorem. Natural discretization schemes for PDEs,
1776     which have these important preservation properties, then follow
1777     by choosing a discrete action functional. In the case of mechanics,
1778     we recover the variational symplectic integrators of Veselov type,

1934     to mechanisms of biological significance in both prokaryotes and

1936     for investigating this phenomenon. Duplex DNA is represented as
1937     a chain of hydrodynamic beads interacting through potentials of
1938     linearly elastic stretching, bending, and twisting, as well as excluded
1939     volume. The chain, linear when relaxed, is looped to form two open
1940     but topologically constrained subdomains. This permits the dynamic
1941     introduction of torsional stress via a centrally applied torque.
1942     We simulate by Brownian dynamics the 100 mus response of a 477-base
1943     pair B-DNA template to the localized torque generated by the prokaryotic
1944     transcription ensemble. Following a sharp rise at early times, the
1945     distributed twist assumes a nearly constant value in both subdomains,
1946     and a succession of supercoiling deformations occurs as superhelical
1947     stress is increasingly partitioned to writhe. The magnitude of writhe
1948     surpasses that of twist before also leveling off when the structure
1949     reaches mechanical equilibrium with the torsional load. Superhelicity
1950     is simultaneously right handed in one subdomain and left handed

2406     backward error analysis can be used to show that a symplectic method
2407     will conserve energy over exponentially long periods of time. Such
2408     results are typically based on two aspects of backward error analysis:
2409     (i) It can be shown that the modified vector fields have some qualitative
2410     properties which they share with the given problem and (ii) an estimate
2411     is given for the difference between the best interpolating vector
2412     field and the numerical method. These aspects have been investigated

2530 tim 2797 limiting factor to increasing the timestep in multiple-timestep
2531     (MTS) biomolecular dynamics simulations. At certain timesteps correlated
2532     to internal motions (e.g., 5 fs, around half the period of the fastest
2533     bond stretch, T-min), visible inaccuracies or instabilities can
2534     occur. Impulse-MTS schemes are vulnerable to these resonance errors
2535     since large energy pulses are introduced to the governing dynamics
2536     equations when the slow forces are evaluated. We recently showed
2537     that such resonance artifacts can be masked significantly by applying
2538     extrapolative splitting to stochastic dynamics. Theoretical and
2539     numerical analyses of force-splitting integrators based on the Verlet
2540     discretization are reported here for linear models to explain these
2541     observations and to suggest how to construct effective integrators
2542     for biomolecular dynamics that balance stability with accuracy.
2543     Analyses for Newtonian dynamics demonstrate the severe resonance
2544     patterns of the Impulse splitting, with this severity worsening
2545     with the outer timestep. Delta t: Constant Extrapolation is generally
2546     unstable, but the disturbances do not grow with Delta t. Thus. the
2547     stochastic extrapolative combination can counteract generic instabilities
2548     and largely alleviate resonances with a sufficiently strong Langevin
2549     heat-bath coupling (gamma), estimates for which are derived here
2550     based on the fastest and slowest motion periods. These resonance
2551     results generally hold for nonlinear test systems: a water tetramer
2552     and solvated protein. Proposed related approaches such as Extrapolation/Correction
2553     and Midpoint Extrapolation work better than Constant Extrapolation
2554     only for timesteps less than T-min/2. An effective extrapolative
2555     stochastic approach for biomolecules that balances long-timestep
2556     stability with good accuracy for the fast subsystem is then applied
2557     to a biomolecule using a three-class partitioning: the medium forces
2558     are treated by Midpoint Extrapolation via position Verlet, and the
2559     slow forces are incorporated by Constant Extrapolation. The resulting
2560     algorithm (LN) performs well on a solvated protein system in terms
2561     of thermodynamic properties and yields an order of magnitude speedup
2562     with respect to single-timestep Langevin trajectories. Computed
2563     spectral density functions also show how the Newtonian modes can
2564     be approximated by using a small gamma in the range Of 5-20 ps(-1).

2865     isotropic-smectic A-smectic B and isotropic-smectic B at high (T*=2.0)
2866     and low (T*=1.5) temperatures, respectively. With increasing quadrupole
2867     magnitude the smectic phases are observed to be stabilized with
2868     respect to the isotropic liquid, while the smectic B is destabilized
2869     with respect to the smectic A. At the lower temperature, a sufficiently
2870     large quadrupole magnitude results in the injection of the smectic
2871     A phase into the phase sequence and the replacement of the smectic
2872     B phase by the tilted smectic J phase. The nematic phase is also
2873     injected into the phase sequence at both temperatures considered,
2874     and ultimately for sufficiently large quadrupole magnitudes no coherent
2875     layered structures were observed. The stabilization of the smectic
2876     A phase supports the commonly held belief that, while the inclusion
2877     of polar groups is not a prerequisite for the formation of the smectic
2878     A phase, quadrupolar interactions help to increase the temperature
2879     and pressure range for which the smectic A phase is observed. The
2880     quality of the layered structure is worsened with increasing quadrupole
2881     magnitude. This behavior, along with the injection of the nematic
2882     phase into the phase sequence, indicate that the general tendency
2883     of the quadrupolar interactions is to destabilize the layered structure.
2884     A pressure dependence upon the smectic layer spacing is observed.

2905     transparent method permitting the evaluation of the Coulomb potential
2906     by direct summation over the r(-1) Coulomb pair potential is presented.
2907     The key observation is that the problems encountered in determining
2908     the Coulomb energy by pairwise, spherically truncated r(-1) summation
2909     are a direct consequence of the fact that the system summed over
2910     is practically never neutral. A simple method is developed that
2911     achieves charge neutralization wherever the r(-1) pair potential
2912     is truncated. This enables the extraction of the Coulomb energy,
2913     forces, and stresses from a spherically truncated, usually charged
2914     environment in a manner that is independent of the grouping of the
2915     pair terms. The close connection of our approach with the Ewald
2916     method is demonstrated and exploited, providing an efficient method
2917     for the simulation of even highly disordered ionic systems by direct,
2918     pairwise r(-1) summation with spherical truncation at rather short
2919     range, i.e., a method which fully exploits the short-ranged nature
