abstract A putative aminotransferase gene, kanB, lies in the biosynthetic gene cluster of Streptomyces kanamyceticus ATCC 12853 and has 66% identity with neo6 in neomycin biosynthesis. Streptomyces fradiae Deltaneo6::tsr was generated by disrupting neo6 in the neomycin producer Streptomyces fradiae. Neomycin production was completely abolished in the disruptant mutant but was restored through self-complementation of neo6. S. fradiae HN4 was generated through complementation with kanB in Streptomyces fradiae neo6::tsr. Based on metabolite analysis by ESI/MS and LC/MS, neomycin production was restored in Streptomyces fradiae HN4. Thus, like neo6, kanB also functions as a 2-deoxy-scyllo-inosose aminotransferase that has dual functions in the formation of 2-deoxy-scyllo-inosose (DOS).
