Pivotal role for the ubiquitin Y59-E51 loop in lysine 48 polyubiquitination [PDF]

Proceedings of the National Academy of Sciences, 2014
Significance Our identification and characterization of the ubiquitin (Ub) Y59-E51 loop have uncovered a pivotal determinant for lysine 48 (K48) linkage-specific Ub chain synthesis catalyzed by Cdc34 E2 Ub-conjugating enzyme. The Ub Y59-E51 loop appears to anchor a Cdc34 E2-engaging zone, allowing the landing of E2 and enabling it to gain ...
