GO:0034450: ubiquitin-ubiquitin ligase activity (Molecular function)

"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." [GOC:mah, GOC:mcc, PMID:10089879, PMID:17190603]
