Dynamics: A key to protein function

Research output: Chapter in Book/Report/Conference proceedingChapter


Proteins are complex entities created from 20 types of amino acids. The diverse functionality of proteins originates from the spatial organization of the protein chain. This brings residues that are far from sequence into proximity and enables the coordinated action of chemical groups. The cleavage of an amide bond, for example, requires an attacking nucleophile and a general acid to activate the nucleophile. Although the variety of three-dimensional architectures (i.e., folds) results in versatile functions, the static arrangement of amino acids cannot fulfill even the simplest biological activity. Binding of oxygen to hemoglobin would be hindered by steric conflicts unless protein sidechains change their position to create a free path toward the heme group.
