ENZYME entry: EC 6.2.1.19

Accepted Name
Long-chain-fatty-acid--protein ligase.
Alternative Name(s)
Acyl-protein synthetase.
Reaction catalysed
ATP + a long-chain fatty acid + [protein]-L-cysteine <=> AMP + diphosphate + a [protein]-S-(long-chain-acyl)-L-cysteine
Comment(s)
  • Together with a hydrolase component (EC 3.1.2.2/3.1.2.14) and a reductase component (EC 1.2.1.50), this enzyme forms a multienzyme fatty acid reductase complex that produces the long-chain aldehyde substrate of the bacterial luciferase enzyme (EC 1.14.14.3).
  • The enzyme activates free long-chain fatty acids, generated by the action of the transferase component, forming a fatty acyl-AMP intermediate, followed by the transfer of the acyl group to an internal L-cysteine residue.
  • It then transfers the acyl group to EC 1.2.1.50.
