ID 4.1.99.26 DE 3-amino-5-[(4-hydroxyphenyl)methyl]-4,4-dimethylpyrrolidin-2-one DE synthase. CA [mycofactocin precursor peptide]-C-terminal glycyl-N- CA {[2-(4-hydroxyphenyl)ethenyl]-3-methylbutanamide} + AH2 + S-adenosyl-L- CA methionine = 5'-deoxyadenosine + [mycofactocin precursor peptide]-C- CA terminal glycyl-N-{5-[(4-hydroxyphenyl)methyl]-4,4-dimethyl-2- CA oxopyrrolidin-3-yl}acetamide + A + H(+) + 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 reaction occurs in the right-to-left direction. CC -!- The other activity of the enzyme is EC 1.3.98.7.
