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].

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].

This prosthetic group acts as a a 'swinging arm' for the attachment of activated fatty acid and amino-acid groups. This domain forms a four helix bundle. This family includes members not included in Prosite. The inclusion of these members is supported by sequence analysis and functional evidence. The related domain of Swiss:P19828 has the attachment serine replaced by an alanine.
