Main chain and side chain dynamics of the ubiquitin conjugating enzyme variant human Mms2 in the free and ubiquitin-bound States.

Abstract excerpt

Protein ubiquitination involves a cascade of enzymatic steps where ubiquitin (Ub) is sequentially transferred as a thiolester intermediate from an E1 enzyme to an E2 enzyme and finally to the protein target with the help of a Ub-protein ligase. Protein ubiquitination brought about by the Ubc13-Mms2 (E2-E2) complex has a unique role in the cell, unrelated to protein degradation. The Mms2-Ubc13 heterodimer links Ub...
