2.3.1.332 |
| Accepted name: |
medium-chain-alcohol O-fatty-acyltransferase |
| Reaction: |
acyl-CoA + a medium-chain alcohol = CoA + a medium-chain alcohol wax ester |
| Other name(s): |
wax synthase (ambiguous); wax-ester synthase (ambiguous) |
| Systematic name: |
acyl-CoA:medium-chain-alcohol O-acyltransferase |
| Comments: |
The enzyme transfers an acyl group from an acyl-CoA to a medium-chain fatty alcohol, forming a wax ester. Wax esters have diverse biological functions in bacteria, insects, mammals, and terrestrial plants.The enzyme from the plant Petunia × hybrida prefers medium chain alcohols and saturated very long-chain acyl-CoAs. The human enzyme AWAT1 prefers decan-1-ol (C10) and has lower activity with C16, C18, and C20 alcohols. cf. EC 2.3.1.75, long-chain-alcohol O-fatty-acyltransferase. |
