Function
function
Catalyzes the first and rate-limiting reaction of the four reactions that constitute the long-chain fatty acids elongation cycle. This endoplasmic reticulum-bound enzymatic process allows the addition of 2 carbons to the chain of long- and very long-chain fatty acids (VLCFAs) per cycle. Condensing enzyme that acts specifically toward polyunsaturated acyl-CoA with the higher activity toward C18:3(n-6) acyl-CoA. May participate to the production of monounsaturated and of polyunsaturated VLCFAs of different chain lengths that are involved in multiple biological processes as precursors of membrane lipids and lipid mediators.
Catalytic activity
- (11Z)-octadecenoyl-CoA + H+ + malonyl-CoA = 3-oxo-(13Z)-eicosenoyl-CoA + CO2 + CoAThis reaction proceeds in the forward direction.
- (5Z,8Z,11Z,14Z)-eicosatetraenoyl-CoA + H+ + malonyl-CoA = (7Z,10Z,13Z,16Z)-3-oxodocosatetraenoyl-CoA + CO2 + CoAThis reaction proceeds in the forward direction.
- (6Z,9Z,12Z)-octadecatrienoyl-CoA + H+ + malonyl-CoA = (8Z,11Z,14Z)-3-oxoeicosatrienoyl-CoA + CO2 + CoAThis reaction proceeds in the forward direction.
- (6Z,9Z,12Z,15Z)-octadecatetraenoyl-CoA + H+ + malonyl-CoA = (8Z,11Z,14Z,17Z)-3-oxoicosatetraenoyl-CoA + CO2 + CoAThis reaction proceeds in the forward direction.
- (9Z)-hexadecenoyl-CoA + H+ + malonyl-CoA = 3-oxo-(11Z)-octadecenoyl-CoA + CO2 + CoAThis reaction proceeds in the forward direction.
- (9Z)-octadecenoyl-CoA + H+ + malonyl-CoA = (11Z)-3-oxoicosenoyl-CoA + CO2 + CoAThis reaction proceeds in the forward direction.
- (9Z,12Z)-octadecadienoyl-CoA + H+ + malonyl-CoA = (11Z,14Z)-3-oxoicosa-11,14-dienoyl-CoA + CO2 + CoAThis reaction proceeds in the forward direction.
- (9Z,12Z,15Z)-octadecatrienoyl-CoA + H+ + malonyl-CoA = (11Z,14Z,17Z)-3-oxoeicosatrienoyl-CoA + CO2 + CoAThis reaction proceeds in the forward direction.
