EC 2.5.1.106     
Accepted name: tryprostatin B synthase
Reaction: prenyl diphosphate + brevianamide F = diphosphate + tryprostatin B

Glossary: brevianamide F = (3S,8aS)-3-(1H-indol-3-ylmethyl)hexahydropyrrolo[1,2-a]pyrazine-1,4-dione
tryprostatin B = (3S,8aS)-3-{[2-(3-methylbut-2-en-1-yl)-1H-indol-3-yl]methyl}hexahydropyrrolo[1,2-a]pyrazine-1,4-dione
Other name(s): ftmPT1 (gene name); brevianamide F prenyltransferase (ambiguous); dimethylallyl-diphosphate:brevianamide-F dimethylallyl-C-2-transferase
Systematic name: prenyl-diphosphate:brevianamide-F prenyl-C-2-transferase
Comments: 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.

EC 2.5.1.109     
Accepted name: brevianamide F prenyltransferase (deoxybrevianamide E-forming)
Reaction: prenyl diphosphate + brevianamide F = diphosphate + deoxybrevianamide E

Glossary: brevianamide F = (3S,8aS)-3-(1H-indol-3-ylmethyl)hexahydropyrrolo[1,2-a]pyrazine-1,4-dione
deoxybrevianamide E = (3S,8aS)-3-{[2-(2-methylbut-3-en-2-yl)-1H-indol-3-yl]methyl}-octahydropyrrolo[1,2-a]piperazine-1,4-dione
Other name(s): NotF; BrePT; brevianamide F reverse prenyltransferase; dimethylallyl-diphosphate:brevianamide-F tert-dimethylallyl-C-2-transferase
Systematic name: prenyl-diphosphate:brevianamide-F 2-methylbut-3-en-2-yl-C-2-transferase
Comments: The enzyme from the fungus Aspergilus sp. MF297-2 is specific for brevianamide F [1], while the enzyme from Aspergillus versicolor accepts a broad range of trytophan-containing cyclic dipeptides [2]. Involved in the biosynthetic pathways of several indole alkaloids such as paraherquamides and malbrancheamides.
