SYSTEMATIC NAME

dimethylallyl-diphosphate:brevianamide-F dimethylallyl-C-2-transferase
The enzyme from the fungus Aspergillus fumigatus can also prenylate other tryptophan-containing cyclic dipeptides. Prenylation occurs mainly at C-2 [1], but also at C-3 [2]. Involved in the biosynthetic pathways of several indole alkaloids such as tryprostatins, cyclotryprostatins, spirotryprostatins, fumitremorgins and verruculogen.

crystal structures of unliganded enzyme FtmPT1 to 2.5 A resolution as well as of a ternary complex of FtmPT1 bound to brevianamide F and an analogue of its isoprenoid substrate dimethylallyl diphosphate. FtmPT1 assumes a rare alpha/beta-barrel fold, consisting of 10 circularly arranged -strands surrounded by alpha-helices. Catalysis is performed in a hydrophobic reaction chamber at the center of the barrel
