Catalyzes the conversion of dTDP-4-dehydro-6-deoxy-D-glucose (dTDP-D-Glc4O) to dTDP-4-amino-4,6-dideoxy-D-glucose (dTDP-D-Qui4N). L-glutamine can also be used as amino donor. 2-oxoglutarate + dTDP-4-amino-4,6-dideoxy-D-glucose = dTDP-4-dehydro-6-deoxy-alpha-D-glucose + L-glutamate Optimum temperature is 37 degrees Celsius. Bacterial outer membrane biogenesis; lipopolysaccharide biosynthesis. Belongs to the DegT/DnrJ/EryC1 family.
