General Information

General Information Comment Organism
metabolism the enzyme is involved in the biosynthesis of the 2-deoxystreptamine (DOS)-containing aminoglycoside neomycin. 3-Amino-2,3-dideoxy-scyllo-inosose produced by the NeoA reaction is continuously used as substrate for the natural forward transamination catalyzed by NeoB in the 2-deoxystreptamine biosynthesis. NeoB also shows L-glutamine:2-deoxy-scyllo-inosose aminotransferase activity resulting in formation of 2-deoxy-scyllo-inosamine, EC 2.6.1.100 Streptomyces fradiae
additional information the equivalent of gene neoB, from neo gene cluster, in the btr gene cluster is gene btrS Streptomyces fradiae
