Systematic name: | [E2 ubiquitin-conjugating enzyme]-S-ubiquitinyl-L-cysteine:acceptor protein ubiquitin transferase (isopeptide bond-forming; RCR-type) | ||
Comments: | RCR-type E3 ubiquitin transferases is a class of RING-type E3 ubiquitin transferase (see EC 2.3.2.27) that mediates ubiquitylation of acceptor proteins via an internal cysteine residue. The RING1 domain binds an EC 2.3.2.23, E2 ubiquitin-conjugating enzyme, and transfers the ubiquitin that is bound to it to an internal cysteine residue on a mediator loop of the RCR-type ligase. The ubiquitin may be transferred to a second internal cysteine before the transfer of the ubiquitin from the RCR-type ligase to the substrate. | ||
