(acyl-carrier-protein) S-acetyltransferase

From Wikipedia, the free encyclopedia

In enzymology, a [acyl-carrier-protein] S-acetyltransferase (EC 2.3.1.38) is an enzyme that catalyzes the chemical reaction

acetyl-CoA + [acyl-carrier-protein] \rightleftharpoons CoA + acetyl-[acyl-carrier-protein]

Thus, the two substrates of this enzyme are acetyl-CoA and acyl-carrier-protein, whereas its two products are CoA and acetyl-acyl-carrier-protein.

This enzyme belongs to the family of transferases, specifically those acyltransferases transferring groups other than aminoacyl groups. The systematic name of this enzyme class is acetyl-CoA:[acyl-carrier-protein] S-acetyltransferase. Other names in common use include acetyl coenzyme A-acyl-carrier-protein transacylase, [acyl-carrier-protein]acetyltransferase, [ACP]acetyltransferase, and ACAT. This enzyme participates in fatty acid biosynthesis.
