Accepted name: fumigaclavine B O-acetyltransferase
Reaction: acetyl-CoA + fumigaclavine B = CoA + fumigaclavine A
Glossary: fumigaclavine B = 6,8β-dimethylergolin-9-ol;
fumigaclavine A = 6,8β-dimethylergolin-9β-yl acetate
Other name(s): FgaAT
Systematic name: acetyl-CoA:fumigaclavine B O-acetyltransferase
Comments: The enzyme participates in the biosynthesis of fumigaclavine C, an ergot alkaloid produced by some fungi of the Trichocomaceae family.

Accepted name: fumigaclavine A dimethylallyltransferase
Reaction: fumigaclavine A + prenyl diphosphate = fumigaclavine C + diphosphate
Glossary: fumigaclavine A = 6,8β-dimethylergolin-9β-yl acetate;
fumigaclavine C = 6,8β-dimethyl-2-(2-methylbut-3-en-2-yl)ergolin-9β-yl acetate
Other name(s): FgaPT1; dimethylallyl-diphosphate:fumigaclavine A dimethylallyltransferase
Systematic name: prenyl-diphosphate:fumigaclavine A prenyltransferase
Comments: Fumigaclavine C is an ergot alkaloid produced by some fungi of the Trichocomaceae family. Activity does not require any metal ions.
