Cooperative omega loops in cytochrome c: role in folding and function.

Mallela M G Krishna1, Yan Lin, Jon N Rumbley, S Walter Englander.   

Abstract

Hydrogen exchange experiments under slow exchange conditions show that an omega loop in cytochrome c (residues 40-57) acts as a cooperative unfolding/refolding unit under native conditions. This unit behavior accounts for an initial step on the unfolding pathway, a final step in refolding, and a number of other structural, functional and evolutionary properties.
