BETA-KETOACYL-ACP SYNTHASE II FROM ESCHERICHIA COLI

Overview

In the biosynthesis of fatty acids, the beta-ketoacyl-acyl carrier protein, (ACP) synthases catalyze chain elongation by the addition of two-carbon, units derived from malonyl-ACP to an acyl group bound to either ACP or, CoA. The crystal structure of beta-ketoacyl synthase II from Escherichia, coli has been determined with the multiple isomorphous replacement method, and refined at 2.4 A resolution. The subunit consists of two mixed, five-stranded beta-sheets surrounded by alpha-helices. The two sheets are, packed against each other in such a way that the fold can be described as, consisting of five layers, alpha-beta-alpha-beta-alpha. The enzyme is a, homodimer, and the subunits are related by a crystallographic 2-fold axis., The two active sites are located near the dimer interface but ... [(full description)]
