B6db activities: rubn4

Description dTDP-3,4-didehydro-2,6-dideoxy-D-glucose aminotransferase (2.6.1.-)
Alternative names rubN4 (gene name);
May7 (gene name);
EvaB (gene name);
Catalyzed reaction dTDP-3,4-didehydro-2,6-dideoxy-D-glucose + L-glutamine = dTDP-3-amino-4-dehydro-2,3,6-trideoxy-D-glucose + 2-oxoglutaramate.
Cofactor Pyridoxal phosphate.
In Streptomyces achromogenes, the activity is required for the biosynthetic pathway leading to the production of the antibiotic rubradirin.
Organisms -Eubacteria
