(acyl-carrier-protein) S-malonyltransferase
In enzymology, a [acyl-carrier-protein] S-malonyltransferase is an enzyme that catalyzes the chemical reaction
malonyl-CoA + acyl carrier protein $\rightleftharpoons$ CoA + malonyl-[acyl-carrier-protein]Thus, the two substrates of this enzyme are malonyl-CoA and acyl carrier protein, whereas its two products are CoA and malonyl-acyl-carrier-protein. This enzyme belongs to the family of transferases, specifically those acyltransferases transferring groups other than aminoacyl groups. This enzyme participates in fatty acid biosynthesis.
