Naturally-occurring and modified recombinant nucleic acid molecules have been isolated that encode linear pre-cursors of cyclopeptides of the Caryophyllaceae (Ccps) and Caryophyllaceae-like (Clcps) type V1 class of cyclopeptides. Such nucleic acid molecules are useful for producing cyclopeptides and their linear precursors by recombinant methods.

Three newcyclic peptides, segetalins B, C and D, were isolated fromVaccariasegetalis (seeds) and their structures were elucidated by 2D NMR and chemical degradations. Conformational analysis of segetalin B, having an estrogen-like effect, was made by using high field NMR and computational methods. Segetalin B was suggested to possess a solution conformation similar to that of segetalin A in the
