Short-time dynamics of polypeptides

Abstract

The authors study the short-time dynamics of helix-forming polypeptide chains using an all-atom representation of the molecules and an implicit solvation model to approximate the interaction with the surrounding solvent. The results confirm earlier observations that the helix-coil transition in proteins can be described by a set of critical exponents. The high statistics of the simulations allows the authors to determine the exponents values with increased precision and support universality of the helix-coil transition in homopolymers and (helical) proteins.
