Accepted name: pre-mycofactocin synthase
Reaction: 3-amino-5-[(4-hydroxyphenyl)methyl]-4,4-dimethylpyrrolidin-2-one + O2 + H2O = 5-[(4-hydroxyphenyl)methyl]-4,4-dimethylpyrrolidine-2,3-dione + NH3 + H2O2 (overall reaction)
(1a) 3-amino-5-[(4-hydroxyphenyl)methyl]-4,4-dimethylpyrrolidin-2-one + O2 = 5-[(4-hydroxyphenyl)methyl]-3-imino-4,4-dimethylpyrrolidin-2-one + H2O2
(1b) 5-[(4-hydroxyphenyl)methyl]-3-imino-4,4-dimethylpyrrolidin-2-one + H2O = 5-[(4-hydroxyphenyl)methyl]-4,4-dimethylpyrrolidine-2,3-dione + NH3 (spontaneous)
Glossary: 5-[(4-hydroxyphenyl)methyl]-4,4-dimethylpyrrolidine-2,3-dione = pre-mycofactocinone = PMFT
Other name(s): mftD (gene name)
Systematic name: 3-amino-5-[(4-hydroxyphenyl)methyl]-4,4-dimethylpyrrolidin-2-one:oxygen oxidoreductase
Comments: A flavoprotein (FMN). The enzyme participates in the biosynthesis of the enzyme cofactor mycofactocin. The enzyme uses oxygen as an electron source to oxidize a C-N bond, followed by spontaneous exchange with water to form an α-keto moiety on the resulting molecule.
