Biosynthesis of aminoglycoside antibiotics: cloning, expression and characterisation of an aminotransferase involved in the pathway to 2-deoxystreptamine.
Huang F., Li Y., Yu J., Spencer J.B.
The gene btrR from Bacillus circulans has been cloned and expressed and shown to produce a protein which catalyses the transamination of 2-deoxy-scyllo-inosose to give 2-deoxy-scyllo-inosamine, an intermediate in the biosynthesis of 2-deoxystreptamine.

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

Identification of L-glutamine: 2-deoxy-scyllo-inosose aminotransferase required for the biosynthesis of butirosin in Bacillus circulans.

Using inverse PCR, two new genes (btrN and btrS) were identified upstream of the putative glycosyltransferase gene btrM in the butirosin-biosynthetic btr gene cluster of Bacillus circulans.

Using inverse PCR, two new genes (btrN and btrS) were identified upstream of the putative glycosyltransferase gene btrM in the butirosin-biosynthetic btr gene cluster of Bacillus circulans. The upstream gene btrS showed significant homology with stsC of Streptomyces griseus, which encodes L-glutamine:scyllo-inosose aminotransferase in the biosynthesis of streptomycin. The function of BtrS was further confirmed by heterologous expression in Escherichia coli and chemical identification of the conversion of 2-deoxy-scyllo-inosose into 2-deoxy-scyllo-inosamine. The identification of BtrS as L-glutamine:2-deoxy-scyllo-inosose aminotransferase is the first report of the aminotransferase gene responsible for 2-deoxystreptamine biosynthesis. << Less

The biosynthetic gene cluster of the 2-deoxystreptamine (DOS)-containing aminoglycoside antibiotic neomycin has been cloned for the first time by screening of a cosmid library of Streptomyces fradiae NCIMB 8233. Sequence analysis has identified 21 putative open reading frames (ORFs) in the neomycin gene cluster (neo) with significant protein sequence similarity to gene products involved in the biosynthesis of other DOS-containing aminoglycosides, namely butirosin (btr), gentamycin (gnt), tobramycin (tbm) and kanamycin (kan). Located at the 5'-end of the neo gene cluster is the previously-characterised neomycin phosphotransferase gene (apH). Three genes unique to the neo and btr clusters have been revealed by comparison of the neo cluster to btr, gnt, tbm and kan clusters. This suggests that these three genes may be involved in the transfer of a ribose moiety to the DOS ring during the antibiotic biosynthesis. The product of the neo-6 gene is characterised here as the L-glutamine : 2-deoxy-scyllo-inosose aminotransferase responsible for the first transamination in DOS biosynthesis, which supports the assignment of the gene cluster. << Less
