Analysis of ribosomes from viomycin-sensitive and -resistant strains of Mycobacterium smegmatis.
نویسندگان
چکیده
Viomycin-resistant strains were isolated from Mycobacterium smegmatis. Ribosomes were isolated and tested for drug resistance in subcellular systems containing poly(U) as messenger ribonucleic acid. Resistance to viomycin in these strains was due to altered ribosomes. Further analysis showed that viomycin resistance of two mutants with low level resistance (20 mug/ml) was due to altered 30S ribosomal subunits. Another mutant that was highly resistant to viomycin (1 mg/ml), however, had altered 50S ribosomal subunits.

Pleiotropic antibiotic resistance mutations associated with ribosomes and ribosomal subunits in Mycobacterium smegmatis.
Viomycin-resistant strains isolated from Mycobacterium smegmatis demonstrated pleiotropic resistance to tuberactinomycin-N, capreomycin, streptomycin, and kanamycin as a result of mutational alteration of ribosomes, even though they were selected for resistance to a single antibiotic. The pleiotropic drug resistance of three mutants isolated by stepwise selection for resistance to viomycin was ...
متن کاملMolecular analysis of kanamycin and viomycin resistance in Mycobacterium smegmatis by use of the conjugation system.
We examined the molecular mechanisms of resistance to kanamycin and viomycin in Mycobacterium smegmatis. All of the M. smegmatis strains with high-level kanamycin resistance had a nucleotide substitution from A to G at position 1389 of the 16S rRNA gene (rrs). This position is equivalent to position 1408 of Escherichia coli, and mutation at this position is known to cause aminoglycoside resista...
متن کاملAltered ribosomes in antibiotic-resistant mutants of Mycobacterium smegmatis.
Two alleles for viomycin-capreomycin resistance (vic) in Mycobacterium smegmatis affect ribosome structures. One (vicA) affects a component of 50S subunits and the other (vicB) affects a component of 30S subunits. The locus for neomycin-kanamycin resistance (nek), which is linked to vicA and vicB, affects a component of 30S subunits. Although the erythromycin resistance locus (ery) is linked to...

that VMinhibits protein synthesis was first shown in intact Mycobacterium aviurrP and it is a ribosomal inhibitor since VM resistance of certain mutants of Mycobacterium smegmatis and Mycobacterium tuberculosis can be attributed to an alteration of ribosomes4~7). The characteristics of VMbinding to ribosomes have been studied. The drug reduced the amounts of [3H]dihydrostreptomycin bound to rib...
متن کاملAlteration of ribosomes and RNA polymerase in drug-resistant clinical isolates of Mycobacterium tuberculosis.
The biochemical mechanism of resistance to kanamycin, viomycin, and rifampin in five clinical isolates of Mycobacterium tuberculosis was studied. Resistance to viomycin and kanamycin was attributed to altered ribosomes, whereas resistance to rifampin was attributed to an alteration of RNA polymerase. Ribosomal resistance was, however, not the only way of expressing resistance to viomycin and ka...
