We investigate the formation of β-sheet structures in proteins without sequence-dependent side-chain interactions. To accomplish this, we introduce a model which explicitly incorporates both solvation effects and the angular dependence (on the protein backbone) of hydrogen bond formation. The thermodynamics of this model is studied by exploring the density of states for the entire system and the local couplings in a partially folded structure. Our results suggest that solvation dynamics…

Self-assembly of peptides into a β-barrel motif
We report the results of a study of the self-assembly of four minimalist peptide strands with a native β-barrel structure. Using a soft-well potential to mimic cellular crowding, molecular dynamics
Folding cooperativity in a 3-stranded β-sheet model
The thermodynamic behavior of a previously designed three-stranded β-sheet was studied via several μs of standard and replica exchange molecular dynamics simulations. The system is shown to populate
H-Bonding Cooperativity Effects in Amyloids: Quantum Mechanical and Molecular Mechanics Study
Abstract The cooperativity effects have been evaluated on three model systems, the formamide, (formylamino)acetamide and amyloidic-layer oligomers with an increasing size of the monomer units (6, 13
Effect of secondary structure on protein aggregation: A replica exchange simulation study
Simulation studies of coarse-grained model oligopeptides that mimic aggregating proteins and a generalized Go model for a set of sequences with varying contents of secondary-structural motifs akin to α-helices and β-sheets are presented.
Probing the kinetic cooperativity of beta-sheet folding perpendicular to the strand direction.
The results together suggest that the relaxation kinetics of DPDPDP can be analyzed according to a two-state model even though its folding may actually involve parallel (but degenerate or nearly degenerate) kinetic pathways.
Thermodynamics of a- and b-Structure Formation in Proteins
An atomic protein model with a minimalistic potential is developed and then tested on an a-helix and a b-hairpin, using exactly the same parameters for both peptides. We find that melting curves for
Generic coarse-grained model for protein folding and aggregation.
The accuracy involved in folding not only the test protein but also other ones show strong evidence for amino acid cooperativity embedded in the model, and the force field is made sure not to be biased toward any particular secondary structure.


Two state behavior in a solvable model of beta-hairpin folding.
A simple model for the formation of a Beta hairpin is described, motivated by the fact that folding of a beta hairpin captures much of the basic physics of protein folding.
How does a beta -hairpin fold/unfold? competition between topology and heterogeneity in a solvable model.
We study the competition between topological effects and sequence inhomogeneities in determining the thermodynamics and the un/folding kinetics of a beta-hairpin. Our work utilizes a new exactly
Folding dynamics with nonadditive forces: A simulation study of a designed helical protein and a random heteropolymer
With this model, all trajectories of a designed protein reach a native like conformation within 0.5 μs although they exhibit some remaining residual fluctuations and a random polymer collapses to several nonspecific compact forms and continues to change its global shape.
Thermodynamics of protein folding: a statistical mechanical study of a small all-beta protein.
The thermodynamic properties of a 46-mer beta-barrel protein model are investigated using Langevin dynamics and the histogram analysis method and the free energy surface of the protein model is characterized from a statistical point of view.
Pressure-induced protein-folding/unfolding kinetics.
It is shown that pressure affects the participation of contacts in the transition state and exponentially decreases the chain reconfigurational diffusion coefficient.
The pressure dependence of hydrophobic interactions is consistent with the observed pressure denaturation of proteins.
The pressure denaturation puzzle is resolved by focusing on the pressure-dependent transfer of water into the protein interior, in contrast to the transfer of nonpolar residues into water, the approach commonly taken in models of protein unfolding.

Cooperativity and stability in a Langevin model of proteinlike folding
Two simplified models of protein dynamics based on Langevin’s equation of motion in a viscous medium are presented and it is found that an isotropic potential energy function produces, at best, a modest degree of cooperativity.
