Comments [?]

FUNCTIONCatalyzes 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. Acts specifically toward polyunsaturated acyl-CoA with the higher activity toward C20:4(n-6) acyl-CoA. Condensing enzyme that catalyzes the synthesis of polyunsaturated very long chain fatty acid (C20- and C22-PUFA). May participate to the production of polyunsaturated VLCFAs of different chain lengths that are involved in multiple biological processes as precursors of membrane lipids and lipid mediators.
CATALYTIC ACTIVITY Reaction=a very-long-chain acyl-CoA + H(+) + malonyl-CoA = a very-long- chain 3-oxoacyl-CoA + CO2 + CoA; Xref=Rhea:RHEA:32727, ChEBI:CHEBI:15378, ChEBI:CHEBI:16526, ChEBI:CHEBI:57287, ChEBI:CHEBI:57384, ChEBI:CHEBI:90725, ChEBI:CHEBI:90736; EC=2.3.1.199;
