A, B	PF02797	Chalcone and stilbene synthases, C-terminal domain (Chal_sti_synt_C)	Chalcone and stilbene synthases, C-terminal domain	This domain of chalcone synthase is reported to be structurally similar to domains in thiolase and beta-ketoacyl synthase. The differences in activity are accounted for by differences in the N-terminal domain.	Domain
