Abstrakt: The crystal structure of the fatty acid elongating enzyme β‐ketoacyl [acyl carrier protein] synthase I (KAS I) from Escherichia colihas been determined to 2.3 Å 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 αβαβα 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.
