Free energy based populations of interconverting microstates of a cyclic peptide lead to the experimental NMR data.
Analysis of nuclear Overhauser enhancement (NOE) intensities data of interconverting microstates of a peptide is a difficult problem in nmr. A new statistical mechanics methodology has been proposedExpand

DETERMINATION OF THE STABLE MICROSTATES OF A PEPTIDE FROM NOE DISTANCE CONSTRAINTS AND OPTIMIZATION OF ATOMIC SOLVATION PARAMETERS
A methodology for analyzing nuclear Overhauser effect (NOE) data of interconverting microstates of a peptide has been suggested recently, which is based on pure statistical mechanical considerations.Expand

Ab initio prediction of the solution structures and populations of a cyclic pentapeptide in DMSO based on an implicit solvation model
Using a recently developed statistical mechanics methodology, the solution structures and populations of the cyclic pentapeptide cyclo(D‐Pro1–Ala2–Ala3–Ala4–Ala5) in DMSO are obtained ab initio,Expand

Efficiency of the Local Torsional Deformations Method for Identifying the Stable Structures of Cyclic Molecules
A new method for generating the low-energy structures of a chain molecule was proposed recently by us. This is a stochastic process where at each step an energy-minimized structure is changed byExpand

NOVEL PROCEDURE FOR DEVELOPING IMPLICIT SOLVATION MODELS FOR PEPTIDES AND PROTEINS
Solvation is an important factor in the structure stabilization of proteins. The free energy of solvation has been commonly approximated by summing the products of the atomic solvation parametersExpand

New conformational search method based on local torsional deformations for cyclic molecules, loops in proteins, and dense polymer systems
We propose a conformational search method, based on local torsional deformations (LTD) for locating the low energy structures of cyclic peptides, loops in proteins or dense polymer systems. LTD isExpand

Efficiency of simulated annealing for peptides with increasing geometrical restrictions
Simulated annealing (SA) is a popular global minimizer that can conveniently be applied to complex macromolecular systems. Thus, a molecular dynamics or a Monte Carlo simulation starts at highExpand

Performance of efficient minimization algorithms as applied to models of peptides and proteins
We test the efficiency of three minimization algorithms as applied to models of peptides and proteins. These include: the limited memory quasi‐Newton (L‐BFGS) of Liu and Nocedal; the truncated NewtonExpand
