IntEnz Enzyme Nomenclature


Accepted name:
tryprostatin B synthase
Other names:
ftmPT1 (gene name)
brevianamide F prenyltransferase [ambiguous]
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.
