Systematic name: |
L-glutamine:2-deoxy-scyllo-inosose aminotransferase |
Comments: |
Involved in the biosynthetic pathways of several clinically important aminocyclitol antibiotics, including kanamycin, butirosin, neomycin and ribostamycin. Also catalyses EC 2.6.1.101, L-glutamine:5-amino-2,3,4-trihydroxycyclohexanone aminotransferase [2]. |
