Catalyzes the transamination of 3-amino-2,3-dideoxy-scyllo-inosose (amino-DOI) into 2-deoxystreptamine (DOS). 3-amino-2,3-dideoxy-scyllo-inosose + L-glutamine = 2-deoxystreptamine + 2-oxoglutaramate Metabolic intermediate biosynthesis; 2-deoxystreptamine biosynthesis; 2-deoxystreptamine from D-glucose 6-phosphate: step 4/4. Antibiotic biosynthesis; kanamycin biosynthesis. Belongs to the DegT/DnrJ/EryC1 family. L-glutamine:2-deoxy-scyllo-inosose/scyllo-inosose aminotransferase subfamily.
