CC -!- FUNCTION: Catalyzes the first and rate-limiting reaction of the four
CC reactions that constitute the long-chain fatty acids elongation cycle.
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 that elongates fatty acids with
CC 12, 14 and 16 carbons with higher activity toward C16:0 acyl-CoAs.
CC Catalyzes the synthesis of unsaturated C16 long chain fatty acids and,
CC to a lesser extent, C18:0 and those with low desaturation degree. May
CC participate in the production of saturated and monounsaturated VLCFAs
CC of different chain lengths that are involved in multiple biological
CC processes as precursors of membrane lipids and lipid mediators.
