Comments [?]

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. 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 RHEA:32727: a very-long-chain acyl-CoA + H(+) + malonyl-CoA = a very-long-chain 3-oxoacyl-CoA + CO2 + CoA
Pathway Lipid metabolism; polyunsaturated fatty acid biosynthesis.
Subcellular location Endoplasmic reticulum membrane; Multi-pass membrane protein.
case <FTTag:ERmotif>
Domain The C-terminal di-lysine motif may confer endoplasmic reticulum localization.
end case
Similarity Belongs to the ELO family. ELOVL2 subfamily.
