ID 1.3.98.7 DE [mycofactocin precursor peptide]-tyrosine decarboxylase. CA [mycofactocin precursor peptide]-C-terminal glycyl-L-valyl-L-tyrosine + CA S-adenosyl-L-methionine = 5'-deoxyadenosine + [mycofactocin precursor CA peptide]-C-terminal glycyl-N-{[2-(4-hydroxyphenyl)ethenyl]-3- CA methylbutanamide} + CO2 + L-methionine. CC -!- This is a bifunctional radical AdoMet (radical SAM) enzyme that CC catalyzes the first two steps in the biosynthesis of the enzyme CC cofactor mycofactocin. CC -!- Activity requires the presence of the MftB chaperone. CC -!- The other activity of the enzyme is EC 4.1.99.26.
