Description |
L-glutamine:3-amino-2,3-dideoxy-scyllo-inosose aminotransferase |
Alternative names |
L-glutamine:5-amino-2,3,4-trihydroxycyclohexanone aminotransferase |
Catalyzed reaction |
L-glutamine + 3-amino-2,3-dideoxy-scyllo-inosose = 2-oxoglutaramate + 2-deoxystreptamine |
Cofactor |
Pyridoxal-phosphate. |
Comments |
Involved in the biosynthetic pathways of several clinically important aminocyclitol antibiotics, including kanamycin, butirosin, neomycin and ribostamycin. Also catalyses EC 2.6.1.100, L-glutamine:2-deoxy-scyllo-inosose aminotransferase.
