Identification, functional and structural characterization of novel aminoglycoside phosphotransferase APH(3″)-Id from Streptomyces rimosus subsp. rimosus ATCC 10970

In this study, we identified a new gene (aph(3″)-Id) coding for a streptomycin phosphotransferase by using phylogenetic comparative analysis of the genome of the oxytetracycline-producing strain Streptomyces rimosus ATCC 10970. Cloning the aph(3″)-Id gene in E.coli and inducing its expression led to an increase in the minimum inhibitory concentration of the recombinant E.coli strain to streptomycin reaching 350 μg/ml. To evaluate the...
