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. Condensing enzyme with higher activity toward C18 acyl-CoAs, especially C18:0 acyl-CoAs. May participate to the production of saturated and monounsaturated 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
Ptm N-Glycosylated.
Similarity Belongs to the ELO family. ELOVL3 subfamily.
