E1 enzymes facilitate conjugation of ubiquitin and ubiquitin-like proteins through adenylation, thioester transfer within E1, and thioester transfer from E1 to E2 conjugating proteins. Early work ...
Ubiquitin and other ubiquitin-like molecules (UBLs) are post-translationally attached to proteins through a sequential enzymatic cascade that uses an E1 activating enzyme, an E2 conjugating enzyme ...
Small ubiquitin-related modifier (SUMO) — which is attached to proteins by a pathway involving the E1 enzyme SAE1, the E2 enzyme UBC9 (also known as UBE21) and an E3 ligase (such as PIAS1 and ...
