A	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

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	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
