A new class EC 7, Translocases, has been added to the EC list. It will be part of ENZYME from release 2018_10. Read more about EC 7 here.

ENZYME entry: EC 6.3.4.15

Accepted Name
Biotin--[biotin carboxyl-carrier protein] ligase.
Alternative Name(s)
Acetyl-CoA carboxylase biotin holoenzyme synthetase.
Biotin--[acetyl-CoA carboxylase] synthetase.
Biotin--[acetyl-CoA-carboxylase] ligase.
Biotin--protein ligase.
Reaction catalysed
ATP + biotin + [biotin carboxyl-carrier protein]-L-lysine <=> AMP + diphosphate + [biotin carboxyl-carrier protein]-N(6)-biotinyl-L-lysine
Comment(s)
  • 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.
