β-ketoacyl-[acyl-carrier-protein] synthase III
Cat No.
EXWM-2122
Description
Involved in the dissociated (or type II) fatty-acid biosynthesis system that occurs in plants and bacteria. In contrast to EC 2.3.1.41 (β-ketoacyl-ACP synthase I) and EC 2.3.1.179 (β-ketoacyl-ACP synthase II), this enzyme specifically uses CoA thioesters rather than acyl-ACP as the primer. In addition to the above reaction, the enzyme can also catalyse the reaction of EC 2.3.1.38, [acyl-carrier-protein] S-acetyltransferase, but to a much lesser extent. The enzyme is responsible for initiating both straight- and branched-chain fatty-acid biosynthesis, with the substrate specificity in an organism reflecting the fatty-acid composition found in that organism. For example, Streptococcus pneumoniae, a Gram-positive bacterium, is able to use both straight- and branched-chain (C4-C6) acyl-CoA primers whereas Escherichia coli, a Gram-negative organism, uses primarily short straight-chain acyl CoAs, with a preference for acetyl-CoA.
