FunFam 62425: CG6178

There are 2 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--CoA ligase. [EC: 6.2.1.3]
ATP + a long-chain fatty acid + CoA = AMP + diphosphate + an acyl-CoA.
  • Acts on a wide range of long-chain saturated and unsaturated fatty acids, but the enzymes from different tissues show some variation in specificity.
  • The liver enzyme acts on acids from C(6) to C(20); that from brain shows high activity up to C(24).

Fatty-acyl-CoA synthase. [EC: 2.3.1.86]
Acetyl-CoA + n malonyl-CoA + 2n NADPH = long-chain-acyl-CoA + n CoA + n CO(2) + 2n NADP(+).
  • The enzyme from yeasts (Ascomycota and Basidiomycota) is a multi- functional protein complex composed of two subunits.
  • One subunit catalyzes the reactions EC 1.1.1.100 and EC 2.3.1.41, while the other subunit catalyzes the reactions of EC 2.3.1.38, EC 2.3.1.39, EC 4.2.1.59, EC 1.3.1.10 and EC 1.1.1.279.
  • The enzyme differs from the animal enzyme (EC 2.3.1.85) in that the enoyl reductase domain requires FMN as a cofactor, and the ultimate product is an acyl-CoA (usually palmitoyl-CoA) instead of a free fatty acid.
