IUBMB Comments

The enzyme biotinylates a biotin carboxyl-carrier protein that is part of an acetyl-CoA carboxylase complex, enabling its subsequent carboxylation by EC 6.3.4.14, biotin carboxylase. The carboxyl group is eventually transferred to acetyl-CoA by EC 2.1.3.15, acetyl-CoA carboxytransferase. In some organisms the carrier protein is part of EC 6.4.1.2, acetyl-CoA carboxylase.

The expected taxonomic range for this enzyme is: Bacteria, Archaea, Eukaryota

Synonyms
biotin ligase, bira protein, biotin-protein ligase, biotin holoenzyme synthetase, bacterial bira biotin ligase, biotin acetyl-coa carboxylase ligase, biotin:apocarboxylase ligase, holocarboxylase synthetase 1, group i biotin protein ligase, more
