ID 2.1.1.349 DE toxoflavin synthase. CA (1) 1,6-didemethyltoxoflavin + S-adenosyl-L-methionine = reumycin + CA S-adenosyl-L-homocysteine + H(+). CA (2) reumycin + S-adenosyl-L-methionine = toxoflavin + S-adenosyl-L- CA homocysteine + H(+). CC -!- The enzyme is a dual-specificity methyltransferase that catalyzes the CC last two steps of toxoflavin biosynthesis. CC -!- Toxoflavin is a major virulence factor of several bacterial crop CC pathogens. //
