2.3.2.24 | additional information | ubiquitin thiol ester forms of at least four of five E2s tested catalyze ubiquitin transfer to a number of small amines, in a reaction that does not require E3 enzyme, and only primary amines on primary carbons can serve as ubiquitin acceptors. E3-independent ubiquitin transfer to the small, basic proteins histones H2A and H2B, and cytochrome c, is also observed | Homo sapiens | ? | - |
