The structure of beta-ketoacyl synthase is similar to that of the thiolase family (Pfam:PF00108) and also chalcone synthase. The active site of beta-ketoacyl synthase is located between the N and C-terminal domains. The N-terminal domain contains most of the structures involved in dimer formation and also the active site cysteine [1].	Domain

Polyketide synthase (PKS) catalyzes the biosynthesis of polyketides, which are structurally and functionally diverse natural products in microorganisms and plants [1]. Type I modular PKSs are the large, multifunctional enzymes responsible for the production of a diverse family of structurally rich and often biologically active natural products. The efficiency of acyl transfer at the interfaces of the individual PKS proteins is thought to be governed by helical regions, termed docking domains (dd). Two such N-terminal domains dimerise to form amphipathic parallel alpha-helical coiled coils: dimerisation is essential for protein function [1].	Domain
