Enzyme Information
| 6.3.4.15 |
Biotin--[biotin carboxyl-carrier protein] ligase.
based on mapping to UniProt P06709
ATP + biotin + [biotin carboxyl-carrier protein]-L-lysine = AMP + diphosphate + [biotin carboxyl-carrier protein]-N(6)-biotinyl-L-lysine.
-!- 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. -!- The carboxyl group is eventually transferred to acetyl-CoA by EC 2.1.3.15. -!- In some organisms the carrier protein is part of EC 6.4.1.2.
