Chains	Accession	Name	Description	Comments	Source
A, B	PF02801	Beta-ketoacyl synthase, C-terminal domain (Ketoacyl-synt_C)	Beta-ketoacyl synthase, C-terminal domain	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.	Domain
A, B	PF21089	Polyketide synthase dehydratase domain (PKS_DH_N)	Polyketide synthase dehydratase domain	This domain is part of a dehydratase domain found in diverse PKS enzymes. This domain adopts a HotDog fold.	Domain
A, B	PF00109	Beta-ketoacyl synthase, N-terminal domain (ketoacyl-synt)	Beta-ketoacyl synthase, N-terminal domain	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 m ...	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
A, B	PF14765	Polyketide synthase dehydratase N-terminal domain (PS-DH)	Polyketide synthase dehydratase N-terminal domain	This entry represents the N-terminal HotDog domain of the dehydratase (DH) module of polyketide synthases [1]. Structural analysis shows these DH domains are double hotdogs in which the active site contains a histidine from the N-terminal hotdog and ...	This entry represents the N-terminal HotDog domain of the dehydratase (DH) module of polyketide synthases [1]. Structural analysis shows these DH domains are double hotdogs in which the active site contains a histidine from the N-terminal hotdog and an aspartate from the C-terminal hotdog. Studies have uncovered that a substrate tunnel formed between the DH domains may be essential for loading substrates and unloading products [2].	Domain
A, B	PF22336	RhiE-like, KS-MAT linker domain (RhiE-like_linker)	RhiE-like, KS-MAT linker domain	This entry represents a linker domain found in polyketide synthases, which connects the N-terminal domains with the B-domain as described in RhiE [1-3].	Domain
A, B	PF00698	Acyl transferase domain (Acyl_transf_1)	Acyl transferase domain		Domain
