Description
Requires Co2+. Involved in the biosynthetic pathways of several clinically important aminocyclitol antibiotics, including kanamycin, butirosin, neomycin and ribostamycin. Requires an NAD+ cofactor, which is transiently reduced during the reaction. The enzyme from the bacterium Bacillus circulans forms a complex with the glutamine amidotransferase subunit of pyridoxal 5'-phosphate synthase (EC 4.3.3.6), which appears to stabilize the complex
