FunFam 204: Long-chain-fatty-acid--luciferin-component ligase

There are 1 EC terms in this cluster

Please note: EC annotations are assigned to the full protein sequence rather than individual protein domains. Since a given protein can contain multiple domains, it is possible that some of the annotations below come from additional domains that occur in the same protein, but have been classified elsewhere in CATH.

Note: The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.

EC Term Annotations Evidence
Long-chain-fatty-acid--protein ligase. [EC: 6.2.1.19]
ATP + a long-chain fatty acid + [protein]-L-cysteine = AMP + diphosphate + a [protein]-S-(long-chain-acyl)-L-cysteine.
  • 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.
