Yang-Lee zeros and the helix-coil transition in a continuum model of polyalanine
نویسندگان
چکیده
We calculate the Yang-Lee zeros for characteristic temperatures of the helix-coil transition in a continuum model of polyalanine. The distribution of these zeros differs from predictions of the Zimm-Bragg theory and supports recent claims that polyalanine exhibits a true phase transition. New estimates for critical exponents are presented and the relation of our results to the LeeYang theorem is discussed.

Molecular dynamics studies on the denaturation of polyalanine in the presence of guanidinium chloride at low concentration
Molecular dynamic simulation is a powerful method that monitors all variations in the atomic level in explicit solvent. By this method we can calculate many chemical and biochemical properties of large scale biological systems. In this work all-atom molecular dynamics simulation of polyalanine (PA) was investigated in the presence of 0.224, 0.448, 0.673, 0.897 and 1.122 M of guanidinium chlorid...
متن کاملSolvation model dependency of helix-coil transition in polyalanine.
Helix-coil transitions in polyalanine molecules of length 10 are studied by multi-canonical Monte Carlo simulations. The solvation effects are included by either a distance-dependent dielectric permittivity or by a term that is proportional to the solvent-accessible surface area of the peptide. We found a strong dependence of the characteristics of the helix-coil transition from the details of ...
متن کاملSolution effects and the order of the helix-coil transition in polyalanine
We study helix-coil transitions in an all-atom model of polyalanine. Molecules of up to length 30 residues are investigated by multicanonical simulations. Results from two implicit solvent models are compared with each other and with that from simulations in gas phase. While the helix-coil transition is in all three models a true thermodynamic phase transition, we find that its strength is redu...
متن کاملDirect computation of long time processes in peptides and proteins: reaction path study of the coil-to-helix transition in polyalanine.
The MaxFlux reaction path algorithm was used to isolate optimal transition pathways for the coil-to-helix transition in polyalanine. Eighteen transition pathways, each connecting one random coil configuration with an ideal alpha-helical configuration, were computed and analyzed. The transition pathway energetics and mechanism were analyzed in terms of the progression of the peptide nonbonded co...
متن کاملMonte Carlo simulations of polyalanine using a reduced model and statistics-based interaction potentials.
A coarse-grained residue-residue interaction potential derived from a statistical analysis of the Protein Data Bank is used to investigate the coil-to-helix transition for polyalanine. The interaction potentials depend on the radial distance between interaction sites, as well as the relative orientation of the sites. Two types of interaction sites are present in the model: a site representing t...
