| Term |
ubiquitin-ubiquitin ligase activity |
ID (Ontology) |
GO:0034450 (Gene Ontology) |
| Definition |
Isoenergetic transfer of ubiquitin from one protein to an existing ubiquitin chain via the reaction X-ubiquitin + Y-ubiquitin = Y-ubiquitin-ubiquitin + X, where both the X-ubiquitin and Y-ubiquitin-ubiquitin linkages are thioester bonds between the C-terminal glycine of ubiquitin and a sulfhydryl side group of a cysteine residue.[ PubMed:10089879 PubMed:17190603 ] |
