Chains	Accession	Name	Description	Comments	Source
A, B	PF00195	Chalcone and stilbene synthases, N-terminal domain (Chal_sti_synt_N)	Chalcone and stilbene synthases, N-terminal domain	The C-terminal 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 this N-terminal domain.	Domain
