Term Name:	fatty acid elongase activity
Synonyms:	condensing enzyme, elongation of very long chain fatty acids activity, ELOVL, very-long-chain 3-ketoacyl-CoA synthase, very-long-chain 3-oxoacyl-CoA synthase, very-long-chain beta-ketoacyl-CoA synthase
Definition:	Catalysis of the reaction: a very-long-chain acyl-CoA + H+ + malonyl-CoA = a very-long-chain 3-oxoacyl-CoA + CO2 + CoA. This reaction is the first (condensation) step of the four-step fatty acid elongation cycle in the endoplasmic reticulum that extends fatty acids of C-16 or longer with an additional 2-C unit.
