Universal low-frequency vibrations of proteins from a simple interaction potential.

Physical review. E, Statistical physics, plasmas, fluids, and related interdisciplinary topics - 1 Oct 1999

Nöllmann M, Etchegoin P

Abstract excerpt

A pairwise Born potential connecting the heavy atom sites within a prescribed cutoff, and the equation of motion method (EOM), reproduce the existence of a universal singularity in the low-frequency vibrational density of states of typical globular proteins. This is due to quasilocalization of acoustic waves and an analogy with a similar feature found in glasses is stressed. We explain the dependence of this...
