CC This endoplasmic reticulum-bound enzymatic process allows the addition CC of 2 carbons to the chain of long- and very long-chain fatty acids CC (VLCFAs) per cycle. Condensing enzyme with higher activity toward C18 CC acyl-CoAs, especially C18:0 acyl-CoAs. May participate to the CC production of saturated and monounsaturated VLCFAs of different chain CC lengths that are involved in multiple biological processes as CC precursors of membrane lipids and lipid mediators. CC -!- CATALYTIC ACTIVITY: CC Reaction=a very-long-chain acyl-CoA + H(+) + malonyl-CoA = a very-long- CC chain 3-oxoacyl-CoA + CO2 + CoA; Xref=Rhea:RHEA:32727, CC ChEBI:CHEBI:15378, ChEBI:CHEBI:16526, ChEBI:CHEBI:57287, CC ChEBI:CHEBI:57384, ChEBI:CHEBI:90725, ChEBI:CHEBI:90736; CC EC=2.3.1.199; CC -!- PATHWAY: Lipid metabolism; polyunsaturated fatty acid biosynthesis. CC -!- SUBCELLULAR LOCATION: Endoplasmic reticulum membrane; Multi-pass CC membrane protein. case CC -!- DOMAIN: The C-terminal di-lysine motif may confer endoplasmic reticulum CC localization. end case CC -!- PTM: N-Glycosylated. CC -!- SIMILARITY: Belongs to the ELO family. ELOVL3 subfamily.
