Function
function
Catalyzes the third of the four reactions of the long-chain fatty acids elongation cycle. This endoplasmic reticulum-bound enzymatic process, allows the addition of two carbons to the chain of long- and very long-chain fatty acids/VLCFAs per cycle. This enzyme catalyzes the dehydration of the 3-hydroxyacyl-CoA intermediate into trans-2,3-enoyl-CoA, within each cycle of fatty acid elongation. Thereby, it participates to the production of VLCFAs of different chain lengths that are involved in multiple biological processes as precursors of membrane lipids and lipid mediators.
Catalytic activity
- (3R)-hydroxyhexadecanoyl-CoA = (2E)-hexadecenoyl-CoA + H2OThis reaction proceeds in the forward direction.
Pathway
Lipid metabolism; fatty acid biosynthesis.
