Very-long-chain 3-oxoacyl-CoA synthase
From Wikipedia, the free encyclopedia
Very-long-chain 3-oxoacyl-CoA synthase (EC 2.3.1.199, very-long-chain 3-ketoacyl-CoA synthase, very-long-chain beta-ketoacyl-CoA synthase, condensing enzyme, CUT1, CER6, FAE1, KCS, ELO) is an enzyme with systematic name malonyl-CoA:very-long-chain acyl-CoA malonyltransferase (decarboxylating and thioester-hydrolysing).[1][2][3][4][5][6][7][8] This enzyme catalyses the following chemical reaction
- very-long-chain acyl-CoA + malonyl-CoA very-long-chain 3-oxoacyl-CoA + CO2 + coenzyme A

This is the first component of the elongase, a microsomal protein complex responsible for extending palmitoyl-CoA and stearoyl-CoA to very-long-chain acyl CoAs. (Very-long-chain in this context refers, for example, to the C26 fatty acids involved in the synthesis of phospholipids and ceramides.[2]
