Crystal structure of UBA2ufd-Ubc9: insights into E1-E2 interactions in Sumo pathways

Template:ABSTRACT PUBMED 21209884

Function

[UBA2_YEAST] The dimeric enzyme acts as a SMT3 E1 ligase. It mediates ATP-dependent activation of SMT3 and formation of a thioester with a conserved cysteine residue on AOS1. [UBC9_YEAST] E2 ubiquitin-like--protein ligase mediating SUMO/Smt3 attachment to septins and PCNA. Seems to be involved in degradation of S- (CLB5) and M-phase cyclins (CLB2).[1] [2]
