    The crystal structure of the fatty acid elongating enzyme beta-ketoacyl [acyl carrier protein] synthase I (KAS I) from Escherichia coli has been determined to 2.3 A resolution by molecular replacement using the recently solved crystal structure of KAS II as a search model. The crystal contains two independent dimers in the asymmetric unit. KAS I assumes the thiolase alpha(beta)alpha(beta)alpha fold. Electrostatic potential distribution reveals an acyl carrier protein docking site and a presumed substrate binding pocket was detected extending the active site. Both subunits contribute to each substrate binding site in the dimer.
