ID 2.6.1.114 DE 8-demethyl-8-aminoriboflavin-5'-phosphate synthase. CA L-glutamate + FMN + O(2) + H(2)O + 3 acceptor = 2-oxoglutarate + 8-amino- CA 8-demethylriboflavin 5'-phosphate + CO(2) + 3 reduced acceptor. 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 ; //
