id: GO:0034450
name: ubiquitin-ubiquitin ligase activity
namespace: molecular_function
type: go
obsolete: False

Description: Catalysis of the reaction: ATP + ubiquitin + protein N-ubiquityl(n)lysine = AMP + diphosphate + protein N-ubiquityl(n+1)lysine. This reaction is the ligation of ubiquitin groups, via isopeptide bonds, to extend the length of the multiubiquitin chain attached to a substrate protein.
