A hydrogen bond regulates slow motions in ubiquitin by modulating a β-turn flip.

Journal of molecular biology - 2 Sept 2011

Sidhu Arshdeep, Surolia Avadhesha, Robertson Andrew D, Sundd Monica

Abstract excerpt

Proteins exist as conformational ensembles composed of multiple interchanging substates separated by kinetic barriers. Interconverting conformations are often difficult to probe, owing to their sparse population and transient nature. Here, we report the identification and characterization of a subset of conformations in ubiquitin that participate in microsecond-to-millisecond motions in the amides of Ile23,...
