6'-oxoglucosaminyl:L-glutamate aminotransferase that catalyzes pyridoxal-5'-phosphate-mediated transamination for the conversion of paromamine to neamine in the biosynthetic pathway of butirosin. 2-oxoglutarate + neamine = 6'-oxoparomamine + L-glutamate Antibiotic biosynthesis; butirosin biosynthesis. Belongs to the class-III pyridoxal-phosphate-dependent aminotransferase family.
