Glossary: 12α,13α-dihydroxyfumitremorgin = (5aR,6S,12S,14aS)-5a,6-dihydroxy-9-methoxy-12-(2-methylprop-1-en-1-yl)-1,2,3,5a,6,11,12,14a-octahydro-5H,14H-pyrrolo[1′′,2′′:4′,5′]pyrazino[1′,2′:1,6]pyrido[3,4-b]indole-5,14-dione
fumitremorgin B = (5aR,6S,12S,14aS)-5a,6-dihydroxy-9-methoxy-11-(3-methylbut-2-en-1-yl)-12-(2-methylprop-1-en-1-yl)-1,2,3,5a,6,11,12,14a-octahydro-5H,14H-pyrrolo[1′′,2′′:4′,5′]pyrazino[1′,2′:1,6]pyrido[3,4-b]indole-5,14-dione
Other name(s): ftmH (gene name); FtmPT2
Systematic name: dimethylallyl-diphosphate:12α,13α-dihydroxyfumitremorgin C dimethylallyl-N-1-transferase
Comments: The enzyme from the fungus Aspergillus fumigatus also shows some activity with fumitremorgin C. Involved in the biosynthetic pathways of several indole alkaloids such as fumitremorgins and verruculogen.
