ID 2.6.1.114 DE 8-demethyl-8-aminoriboflavin-5'-phosphate synthase. CA FMN + L-glutamate + 3 A + O2 + H2O = 8-amino-8-demethylriboflavin CA 5'-phosphate + 2-oxoglutarate + 3 AH2 + CO2 + H(+). CC -!- The enzyme, characterized from the bacterium Streptomyces davawensis, CC has the activities of an oxidoreductase, a decarboxylase, and an CC aminotransferase. CC -!- Its combined actions result in the replacement of a methyl CC substituent of one of the aromatic rings of FMN by an amino group, CC a step in the biosynthetic pathway of roseoflavin. CC -!- The reaction requires thiamine for completion. DR K4REZ6, ROSB_STRDJ ; //
