EC number

1.3.98.7

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

Comment

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 4.1.99.26, 3-amino-5-[(4-hydroxyphenyl)methyl]-4,4-dimethylpyrrolidin-2-one synthase.
