1.2.1.84

Accepted name:

alcohol-forming fatty acyl-CoA reductase (NADPH)

Reaction:

a long-chain acyl-CoA + 2 NADPH + 2 H⁺ = a long-chain alcohol + 2 NADP⁺ + CoA

Glossary:

a long-chain acyl-CoA = an acyl-CoA thioester where the acyl chain contains 13 to 22 carbon atoms.

Other name(s):

FAR (gene name); long-chain acyl-CoA:NADPH reductase

Systematic name:

NADPH:long-chain acyl-CoA reductase

Comments:

The enzyme has a wide distribution and is found in bacteria, plants, fungi, and animals. The alcohol is formed by a four-electron reduction of fatty acyl-CoA. Although the reaction proceeds through an aldehyde intermediate, a free aldehyde is not released. Enzymes from different sources vary in their chain-length preference. cf. EC 1.2.1.108, alcohol-forming fatty acyl-CoA reductase (NADH).
