ID 6.3.4.15 DE biotin--[biotin carboxyl-carrier protein] ligase. AN acetyl-CoA carboxylase biotin holoenzyme synthetase. AN biotin--[acetyl-CoA-carboxylase] ligase. AN biotin--[acetyl-CoA carboxylase] synthetase. AN biotin--protein ligase. CA ATP + biotin + L-lysyl-[protein] = AMP + diphosphate + H(+) + N(6)- CA biotinyl-L-lysyl-[protein]. CC -!- The enzyme biotinylates a biotin carboxyl-carrier protein that is CC part of an acetyl-CoA carboxylase complex, enabling its subsequent CC carboxylation by EC 6.3.4.14. CC -!- The carboxyl group is eventually transferred to acetyl-CoA by CC EC 2.1.3.15. CC -!- In some organisms the carrier protein is part of EC 6.4.1.2.
