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

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

1292 tim 2807 with an application to bovine pancreatic trypsin inhibitor (BPTI),
1293     is reported. The unfolding and refolding of the native structure
1294     of the protein are characterized by the dimensions of the protein,
1295     expressed in terms of the three principal radii of the structure
1296     considered as an ellipsoid. A dynamic equation, describing the variations
1297     of the principal radii on the unfolding path, and a numerical procedure
1298     to solve this equation are proposed. Expanded and distorted conformations
1299     are refolded to the native structure by a dimensional-constraint
1300     energy minimization procedure. A unique and reproducible unfolding
1301     pathway for an intermediate of BPTI lacking the [30,51] disulfide
1302     bond is obtained. The resulting unfolded conformations are extended;
1303     they contain near-native local structure, but their longest principal
1304     radii are more than 2.5 times greater than that of the native structure.
1305     The most interesting finding is that the majority of expanded conformations,
1306     generated under various conditions, can be refolded closely to the
1307     native structure, as measured by the correct overall chain fold,
1308     by the rms deviations from the native structure of only 1.9-3.1
1309     angstrom, and by the energy differences of about 10 kcal/mol from
1310     the native structure. Introduction of the [30,51] disulfide bond
1311     at this stage, followed by minimization, improves the closeness
1312     of the refolded structures to the native structure, reducing the
1313     rms deviations to 0.9-2.0 angstrom. The unique refolding of these
1314     expanded structures over such a large conformational space implies
1315     that the folding is strongly dictated by the interactions in the
1316     amino acid sequence of BPTI. The simulations indicate that, under
1317     conditions that favor a compact structure as mimicked by the volume
1318     constraints in our algorithm; the expanded conformations have a
1319     strong tendency to move toward the native structure; therefore,
1320     they probably would be favorable folding intermediates. The results
1321     presented here support a general model for protein folding, i.e.,
1322     progressive formation of partially folded structural units, followed
1323     by collapse to the compact native structure. The general applicability

1343     with the principal aim of gaining a better understanding of the
1344     principal motion types, but also in order to develop more efficient
1345     numerical methods for simulating neutron scattering spectra of large
1346     proteins. First, we decompose a molecular dynamics (MD) trajectory
1347     of 1.5 ns for a C-phycocyanin dimer surrounded by a layer of water
1348     into three contributions that we expect to be independent: the global
1349     motion of the residues, the rigid-body motion of the sidechains
1350     relative to the backbone, and the internal deformations of the sidechains.
1351     We show that they are indeed almost independent by verifying the
1352     factorization of the incoherent intermediate scattering function.
1353     Then, we show that the global residue motions, which include all
1354     large-scale backbone motions, can be reproduced by a simple harmonic
1355     model which contains two contributions: a short-time vibrational
1356     term, described by a standard normal mode calculation in a local
1357     minimum, and a long-time diffusive term, described by Brownian motion
1358     in an effective harmonic potential. The potential and the friction
1359     constants were fitted to the MD data. The major anharmonic contribution
1360     to the incoherent intermediate scattering function comes from the
1361     rigid-body diffusion of the sidechains. This model can be used to
1362     calculate scattering functions for large proteins and for long-time
1363     scales very efficiently, and thus provides a useful complement to
1364     MD simulations, which are best suited for detailed studies on smaller

1384     first approach exploited the fact that the presence of water in
1385     the excited state solvent cage of a fluorophore increases the rate
1386     of decay. For 1,6-diphenyl-1,3,5-hexatriene (DPH) and 1-palmitoyl-2-[[2-[4-(6-phenyl-trans-1,3,5-hexatrienyl)
1387     phenyl]ethyl]carbonyl]-3-sn-PC (DPH-PC), where the fluorophores
1388     are located in the hydrophobic core of the lipid bilayer, the introduction
1389     of gramicidin reduced the fluorescence lifetime, indicative of an
1390     increased presence of water in the bilayer. Since a high protein:lipid
1391     ratio was used, the fluorophores were forced to be adjacent to the
1392     protein hydrophobic surface, hence the presence of water in this
1393     region could be inferred. Cholesterol is known to reduce the water
1394     content of lipid bilayers and this effect was maintained at the
1395     protein-lipid interface with both gramicidin and apocytochrome C,
1396     again suggesting hydration in this region. The second approach was
1397     to use the fluorescence enhancement induced by exchanging deuterium

1399     located in the lipid head group region, and of the gramicidin intrinsic
1400     tryptophans were greater in a D2O buffer compared with H2O, showing
1401     that the fluorophores were exposed to water in the bilayer at the
1402     protein-lipid interface. In the presence of cholesterol the fluorescence
1403     intensity ratio of D2O to H2O decreased, indicating a removal of
1404     water by the cholesterol, in keeping with the lifetime data. Altered

1470     dynamics. More specifically, stable and accurate integrations are
1471     obtained for damping coefficients that are only a few percent of
1472     the natural decay rate of processes of interest, such as the velocity
1473     autocorrelation function. Two new multiple time stepping integrators,
1474     Langevin Molly (LM) and Brunger-Brooks-Karplus-Molly (BBK-M), are
1475     introduced in this paper. Both use the mollified impulse method
1476     for the Newtonian term. LM uses a discretization of the Langevin
1477     equation that is exact for the constant force, and BBK-M uses the
1478     popular Brunger-Brooks-Karplus integrator (BBK). These integrators,
1479     along with an extrapolative method called LN, are evaluated across
1480     a wide range of damping coefficient values. When large damping coefficients
1481     are used, as one would for the implicit modeling of solvent molecules,
1482     the method LN is superior, with LM closely following. However, with
1483     mild damping of 0.2 ps(-1), LM produces the best results, allowing
1484     long time steps of 14 fs in simulations containing explicitly modeled
1485     flexible water. With BBK-M and the same damping coefficient, time
1486     steps of 12 fs are possible for the same system. Similar results
1487     are obtained for a solvated protein-DNA simulation of estrogen receptor
1488     ER with estrogen response element ERE. A parallel version of BBK-M
1489     runs nearly three times faster than the Verlet-I/r-RESPA (reversible
1490     reference system propagator algorithm) when using the largest stable
1491     time step on each one, and it also parallelizes well. The computation
1492     of diffusion coefficients for flexible water and ER/ERE shows that

1578     methods are generally used, This is unfortunate since symplectic
1579     methods like Verlet exhibit superior energy conservation in long-time

1585     of the rotation matrix. We test our method on a system of soft-sphere
1586     dipoles and compare with quaternion evolution using a 4th-order
1587     predictor-corrector integrator, Although the short-time error of
1588     the quaternion algorithm is smaller for fixed time step than that

1612     to be a manifestation of short-range antiparallel association of

1817     abstract = {To obtain insight in the process of water permeation through a lipid
1818     membrane, we performed molecular dynamics simulations on a phospholipid
1819     (DPPC)/water system with atomic detail. Since the actual process
1820     of permeation is too slow to be studied directly, we deduced the
1821     permeation rate indirectly via computation of the free energy and
1822     diffusion rate profiles of a water molecule across the bilayer.
1823     We conclude that the permeation of water through a lipid membrane
1824     cannot be described adequately by a simple homogeneous solubility-diffusion
1825     model. Both the excess free energy and the diffusion rate strongly
1826     depend on the position in the membrane, as a result from the inhomogeneous
1827     nature of the membrane. The calculated excess free energy profile
1828     has a shallow slope and a maximum height of 26 kJ/mol. The diffusion
1829     rate is highest in the middle of the membrane where the lipid density
1830     is low. In the interfacial region almost all water molecules are
1831     bound by the lipid headgroups, and the diffusion turns out to be
1832     1 order of magnitude smaller. The total transport process is essentially
1833     determined by the free energy barrier. The rate-limiting step is
1834     the permeation through the dense part of the lipid tails, where
1835     the resistance is highest. We found a permeation rate of 7(+/-3)
1836     x 10(-2) cm/s at 350 K, comparable to experimental values for DPPC
1837     membranes, if corrected for the temperature of the simulation. Taking
1838     the inhomogeneity of the membrane into account, we define a new
1839     ''four-region'' model which seems to be more realistic than the

1863     to prove covariant generalizations of conservation of symplecticity
1864     and Noether's theorem. Natural discretization schemes for PDEs,

1866     by choosing a discrete action functional. In the case of mechanics,

1992 tim 2807 by computer simulation. The banana-shaped molecules were described
1993     by model intermolecular interactions based on the Gay-Berne potential.
1994     The characteristic molecular structure was considered by joining
1995     two calamitic Gay-Berne particles through a bond to form a biaxial
1996     molecule of point symmetry group C-2v with a suitable bending angle.
1997     The dependence on temperature of systems of N=1024 rigid banana-shaped
1998     molecules with bending angle phi=140degrees has been studied by
1999     means of Monte Carlo simulations in the isobaric-isothermal ensemble
2000     (NpT). On cooling an isotropic system, two phase transitions characterized
2001     by phase transition enthalpy, entropy and relative volume change
2002     have been observed. For the first time by computer simulation of
2003     a many-particle system of banana-shaped molecules, at low temperature
2004     an untilted smectic phase showing a global phase biaxiality and
2005     a spontaneous local polarization in the layers, i.e. a local polar
2006     arrangement of the steric dipoles, with an antiferroelectric-like
2007     superstructure could be proven, a phase structure which recently
2008     has been discovered experimentally. Additionally, at intermediate
2009     temperature a nematic-like phase has been proved, whereas close
2010     to the transition to the smectic phase hints of a spontaneous achiral
2011     symmetry breaking have been determined. Here, in the absence of

2043     to mechanisms of biological significance in both prokaryotes and
2044     eukaryotes. In this paper, we introduce a dynamic computer model
2045     for investigating this phenomenon. Duplex DNA is represented as
2046     a chain of hydrodynamic beads interacting through potentials of
2047     linearly elastic stretching, bending, and twisting, as well as excluded
2048     volume. The chain, linear when relaxed, is looped to form two open
2049     but topologically constrained subdomains. This permits the dynamic
2050     introduction of torsional stress via a centrally applied torque.
2051     We simulate by Brownian dynamics the 100 mus response of a 477-base
2052     pair B-DNA template to the localized torque generated by the prokaryotic
2053     transcription ensemble. Following a sharp rise at early times, the
2054     distributed twist assumes a nearly constant value in both subdomains,
2055     and a succession of supercoiling deformations occurs as superhelical
2056     stress is increasingly partitioned to writhe. The magnitude of writhe
2057     surpasses that of twist before also leveling off when the structure
2058     reaches mechanical equilibrium with the torsional load. Superhelicity
2059     is simultaneously right handed in one subdomain and left handed
2060     in the other, as predicted by the #transcription-induced##twin-supercoiled-domain#

2515     backward error analysis can be used to show that a symplectic method
2516     will conserve energy over exponentially long periods of time. Such
2517     results are typically based on two aspects of backward error analysis:

2572     species (high barrier for Na+, low barrier for K+, almost free diffusion
2573     for water), different methods are used to calculate the mobilities.
2574     By use of activated dynamics and a potential of mean force determined
2575     previously (Roux, B.; Karplus, M. Biophys. J. 1991, 59, 961), the
2576     barrier crossing rate of Na+ ion is determined. The motion of Na+
2577     at the transition state is controlled by local interactions and
2578     collisions with the neighboring carbonyls and the two nearest water
2579     molecules. There are significant deviations from transition-state
2580     theory; the transmission coefficient is equal to 0.11. The water
2581     and K+ motions are found to be well described by a diffusive model;
2582     the motion of K+ appears to be controlled by the diffusion of water.
2583     The time-dependent friction functions of Na+ and K+ ions in the
2584     periodic beta-helix are calculated and analyzed by using a generalized
2585     Langevin equation approach. Both Na+ and K+ suffer many rapid collisions,
2586     and their dynamics is overdamped and noninertial. Thus, the selectivity

2672     abstract = {Numerical resonance artifacts have become recognized recently as a
2673 tim 2807 limiting factor to increasing the timestep in multiple-timestep
2674     (MTS) biomolecular dynamics simulations. At certain timesteps correlated
2675     to internal motions (e.g., 5 fs, around half the period of the fastest
2676     bond stretch, T-min), visible inaccuracies or instabilities can
2677     occur. Impulse-MTS schemes are vulnerable to these resonance errors
2678     since large energy pulses are introduced to the governing dynamics
2679     equations when the slow forces are evaluated. We recently showed
2680     that such resonance artifacts can be masked significantly by applying
2681     extrapolative splitting to stochastic dynamics. Theoretical and
2682     numerical analyses of force-splitting integrators based on the Verlet
2683     discretization are reported here for linear models to explain these
2684     observations and to suggest how to construct effective integrators
2685     for biomolecular dynamics that balance stability with accuracy.
2686     Analyses for Newtonian dynamics demonstrate the severe resonance
2687     patterns of the Impulse splitting, with this severity worsening
2688     with the outer timestep. Delta t: Constant Extrapolation is generally
2689     unstable, but the disturbances do not grow with Delta t. Thus. the
2690     stochastic extrapolative combination can counteract generic instabilities
2691     and largely alleviate resonances with a sufficiently strong Langevin
2692     heat-bath coupling (gamma), estimates for which are derived here
2693     based on the fastest and slowest motion periods. These resonance
2694     results generally hold for nonlinear test systems: a water tetramer
2695     and solvated protein. Proposed related approaches such as Extrapolation/Correction
2696     and Midpoint Extrapolation work better than Constant Extrapolation
2697     only for timesteps less than T-min/2. An effective extrapolative
2698     stochastic approach for biomolecules that balances long-timestep
2699     stability with good accuracy for the fast subsystem is then applied
2700     to a biomolecule using a three-class partitioning: the medium forces
2701     are treated by Midpoint Extrapolation via position Verlet, and the
2702     slow forces are incorporated by Constant Extrapolation. The resulting
2703     algorithm (LN) performs well on a solvated protein system in terms
2704     of thermodynamic properties and yields an order of magnitude speedup
2705     with respect to single-timestep Langevin trajectories. Computed
2706     spectral density functions also show how the Newtonian modes can
2707     be approximated by using a small gamma in the range Of 5-20 ps(-1).

2768 tim 2807 structure and receptor docking mechanism are still not well understood.
2769     The conformational dynamics of this neuron peptide in liquid water
2770     are studied here by using all-atom molecular dynamics (MID) and
2771     implicit water Langevin dynamics (LD) simulations with AMBER potential
2772     functions and the three-site transferable intermolecular potential
2773     (TIP3P) model for water. To achieve the same simulation length in
2774     physical time, the full MID simulations require 200 times as much
2775     CPU time as the implicit water LID simulations. The solvent hydrophobicity
2776     and dielectric behavior are treated in the implicit solvent LD simulations
2777     by using a macroscopic solvation potential, a single dielectric
2778     constant, and atomic friction coefficients computed using the accessible
2779     surface area method with the TIP3P model water viscosity as determined
2780     here from MID simulations for pure TIP3P water. Both the local and
2781     the global dynamics obtained from the implicit solvent LD simulations
2782     agree very well with those from the explicit solvent MD simulations.

3040     respect to the isotropic liquid, while the smectic B is destabilized
3041     with respect to the smectic A. At the lower temperature, a sufficiently

3079     The key observation is that the problems encountered in determining
3080     the Coulomb energy by pairwise, spherically truncated r(-1) summation
3081     are a direct consequence of the fact that the system summed over
3082     is practically never neutral. A simple method is developed that
3083     achieves charge neutralization wherever the r(-1) pair potential
3084     is truncated. This enables the extraction of the Coulomb energy,
3085     forces, and stresses from a spherically truncated, usually charged
3086     environment in a manner that is independent of the grouping of the
3087     pair terms. The close connection of our approach with the Ewald

3089     for the simulation of even highly disordered ionic systems by direct,
