| EC Number | 6.3.4.15 |
| CAS Registry Number | 37340-95-7 |
| 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. |
