ID 1.14.13.187 DE L-evernosamine nitrososynthase. CA dTDP-beta-L-evernosamine + H(+) + 2 NADPH + 2 O2 = dTDP-2,3,6-trideoxy-3- CA C-methyl-4-O-methyl-3-nitroso-beta-L-arabino-hexopyranose + 3 H2O + CA 2 NADP(+). CC -!- Isolated from the bacterium Micromonospora carbonacea var. africana. CC -!- The nitroso group is probably spontaneously oxidized to a nitro group CC giving dTDP-beta-L-evernitrose, which is involved in the biosynthesis CC of the antibiotic everninomycin. CC -!- The reaction was studied using dTDP-beta-L-4-epi-vancosamine (dTDP-4- CC O-desmethyl-beta-L-evernitrosamine). DR C4RPA1, NITSS_MICS3; //
