Biosynthesis of 2-deoxystreptamine by three crucial enzymes in Streptomyces fradiae NBRC 12773.
Kudo F., Yamamoto Y., Yokoyama K., Eguchi T., Kakinuma K.
NeoA, B, and C encoded in the neomycin biosynthetic gene cluster have been enzymatically confirmed to be responsible to the formation of 2-deoxystreptamine (DOS) in Streptomyces fradiae. NeoC was functionally characterized as 2-deoxy-scyllo-inosose synthase, which catalyzes the carbocycle formatio ... >> More
NeoA, B, and C encoded in the neomycin biosynthetic gene cluster have been enzymatically confirmed to be responsible to the formation of 2-deoxystreptamine (DOS) in Streptomyces fradiae. NeoC was functionally characterized as 2-deoxy-scyllo-inosose synthase, which catalyzes the carbocycle formation from D-glucose-6-phosphate to 2-deoxy-scyllo-inosose. Further, NeoA appeared to catalyze the oxidation of 2-deoxy-scyllo-inosamine (DOIA) with NAD(P)+ forming 3-amino-2,3-dideoxy-scyllo-inosose (amino-DOI). Consequently, NeoA was characterized as 2-deoxy-scyllo-inosamine dehydrogenase. Finally, amino-DOI produced by NeoA from DOIA was transformed into DOS by NeoB. Since NeoB (Neo6) was also reported to be L-glutamine:2-deoxy-scyllo-inosose aminotransferase, all the enzymes in the DOS biosynthesis were characterized for the first time. << Less

Heterologous production of paromamine in Streptomyces lividans TK24 using kanamycin biosynthetic genes from Streptomyces kanamyceticus ATCC12853.
Nepal K.K., Oh T.J., Sohng J.K.
The 2-deoxystreptamine and paromamine are two key intermediates in kanamycin biosynthesis. In the present study, pSK-2 and pSK-7 recombinant plasmids were constructed with two combinations of genes: kanABK and kanABKF and kacA respectively from kanamycin producer Streptomyces kanamyceticus ATCC128 ... >> More
The 2-deoxystreptamine and paromamine are two key intermediates in kanamycin biosynthesis. In the present study, pSK-2 and pSK-7 recombinant plasmids were constructed with two combinations of genes: kanABK and kanABKF and kacA respectively from kanamycin producer Streptomyces kanamyceticus ATCC12853. These plasmids were heterologously expressed into Streptomyces lividans TK24 independently and generated two recombinant strains named S. lividans Sk-2/SL and S. lividans SK-7/SL, respectively. ESI/ MS and ESI-LC/MS analysis of the metabolite from S. lividans SK-2/SL showed that the compound had a molecular mass of 163 [M + H]+, which corresponds to that of 2-deoxystreptamine. ESI/MS and MS/MS analysis of metabolites from S. lividans SK-7/SL demonstrated the production of paromamine with a molecular mass of 324 [M + H]+. In this study, we report the production of paromamine in a heterologous host for the first time. This study will evoke to explore complete biosynthetic pathways of kanamycin and related aminoglycoside antibiotics. << Less
