Accepted name: [mycofactocin precursor peptide]-tyrosine decarboxylase
Reaction: C-terminal [mycofactocin precursor peptide]-glycyl-L-valyl-L-tyrosine + S-adenosyl-L-methionine = C-terminal [mycofactocin precursor peptide]-glycyl-L-valyl-4-[2-aminoethenyl]phenol + CO2 + 5′-deoxyadenosine + L-methionine
Other name(s): mftC (gene name)
Systematic name: C-terminal [mycofactocin precursor peptide]-glycyl-L-valyl-L-tyrosine L-tyrosine-carboxylyase
Comments: This is a bifunctional radical AdoMet (radical SAM) enzyme that catalyses the first two steps in the biosynthesis of the enzyme cofactor mycofactocin. Activity requires the presence of the MftB chaperone. The other activity of the enzyme is EC, 3-amino-5-[(4-hydroxyphenyl)methyl]-4,4-dimethylpyrrolidin-2-one synthase.
