Expression of 2-deoxy-scyllo-inosose synthase (kanA) from kanamycin gene cluster in Streptomyces lividans

Biotechnol Lett. 2005 Apr;27(7):465-70. doi: 10.1007/s10529-005-2222-y.


An actinomycetes expression vector (pIBR25) was constructed and applied to express a gene from the kanamycin biosynthetic gene cluster encoding 2-deoxy-scyllo-inosose synthase (kanA) in Streptomyces lividans TK24. The expression of kanA in pIBR25 transformants reached a maximum after 72 h of culture. The plasmid pIBR25 showed better expression than pSET152, and resulted in the formation of insoluble KanA when it was expressed in Escherichia coli. This strategy thus provides a valuable tool for expressing aminoglycoside-aminocyclitols (AmAcs) biosynthetic genes in Streptomyces spp.
