Transposon Tn5 encodes streptomycin resistance in nonenteric bacteria.

چکیده
Strains of Caulobacter crescentus, Pseudomonas putida, Acinetobacter calcoaceticus, Rhizobium meliloti, and Rhodopseudomonas sphaeroides carrying the kanamycin resistance-encoding transposon Tn5 were 15 to 500 times more resistant to streptomycin than transposon-free strains. The streptomycin resistance determinant, which is separable from the kanamycin resistance determinant of Tn5, was not expressed in Escherichia coli or Klebsiella aerogenes.

Host-dependent transposon Tn5-mediated streptomycin resistance.
Transposon Tn5 encodes streptomycin resistance in addition to kanamycin-neomycin resistance. This resistance was not detectable in Escherichia coli but was efficiently expressed in Rhizobium meliloti and certain other strains. By analysis of cloned Tn5 restriction endonuclease fragments, the streptomycin resistance (str) gene was located in the right-hand side of the central region as the trans...
متن کاملMini-Tn5 transposon derivatives for insertion mutagenesis, promoter probing, and chromosomal insertion of cloned DNA in gram-negative eubacteria.
A collection of Tn5-derived minitransposons has been constructed that simplifies substantially the generation of insertion mutants, in vivo fusions with reporter genes, and the introduction of foreign DNA fragments into the chromosome of a variety of gram-negative bacteria, including the enteric bacteria and typical soil bacteria like Pseudomonas species. The minitransposons consist of genes sp...
متن کاملChloramphenicol transposons found in Salmonella naestved and Escherichia coli of domestic animal origin.
Salmonella naestved strain AHI-21, of calf origin, harbors a conjugative R plasmid of group H1, pTE21, which encodes resistance to chloramphenicol (Cm), tetracycline, streptomycin, and sulfadimethoxine. Escherichia coli strain AHI-1, of pig origin, also harbors a conjugative R plasmid of group I alpha, pTE1, which encodes resistance to chloramphenicol and trimethoprim. When either of these R pl...
متن کاملBroad-host-range plasmid pRK340 delivers Tn5 into the Legionella pneumophila chromosome.
Transposon Tn5 was introduced into Legionella pneumophila on plasmid pRK340, which is temperature sensitive for plasmid maintenance. The presence of plasmid DNA was confirmed by agarose gel electrophoresis and by conjugal transfer of the plasmid to Escherichia coli. Tn5 insertions were obtained by culturing L. pneumophila at the nonpermissive temperature (43 degrees C) on buffered charcoal-yeas...
متن کاملTransposon mutagenesis of the anaerobic commensal, Bacteroides fragilis, using the EZ::TN5 transposome.
Genetic analysis of Bacteroides fragilis (BF) is hindered because of the lack of efficient transposon mutagenesis methods. Here, we describe a simple method for transposon mutagenesis using EZ::TN5, a commercially available system that we optimized for use in BF638R. The modified EZ::TN5 transposon contains an Escherichia coli conditional origin of replication, a kanamycin resistance gene for E...
