Escherichia coli K-12 auxotrophs induced by insertion of the transposable element Tn5.
نویسندگان
چکیده
The sites of insertion of the transposable kanamycin-neomycin resistance-determining element, Tn5, in the E. coli K-12 chromosome were assessed in a collection of over 300 auxotrophs. Although mutations in at least 45 different cistrons were obtained, the distribution of insertion sites was not completely random: proA or proB; cysG; and cysH, cysD or cysC mutants were found in excess.

Escherichia coli K-12 mutation that inactivates biodegradative threonine dehydratase by transposon Tn5 insertion.
From a collection of kanamycin-resistant mutants of Escherichia coli K-12 isolated by transposon Tn5 mutagenesis, we have identified a mutant that lacks functional biodegradative threonine dehydratase (EC 4.2.1.16) by direct enzyme assay and by the loss of cross-reacting material with affinity-purified antibodies against the purified enzyme. Aerobic and anaerobic growth of this strain on variou...
متن کاملTransposition of IS2 into the hemB gene of Escherichia coli K-12.
Genetic studies of the hemB gene in Escherichia coli have resulted in the recovery of both stable and unstable mutant strains. The stable strains have been shown to result from large deletions. This study demonstrates that unstable strains result from the insertion of transposable element IS2 primarily into the 5' region of the structural gene; the instability results from precise excision of t...
متن کاملSymbiotic characteristics of cysteine and methionine auxotrophs of Sinorhizobium meliloti.
Twenty one cysteine and 13 methionine auxotrophs of Sinorhizobium meliloti Rmd201 were obtained by random mutagenesis with transposon Tn5. The cysteine auxotrophs were sulfite reductase mutants and each of these auxotrophs had a mutation in cysI/cysJ gene. The methionine auxotrophs were metA/metZ, metE and metF mutants. One hundred per cent co-transfer of Tn5-induced kanamycin resistance and au...
متن کاملEvolution of transposons: natural selection for Tn5 in Escherichia coli K12.
A novel in vivo effect of the transposable element Tn5 has been observed in chemostats when certain isogenic Tn5 and non-Tn5 strains of Escherichia coli compete for a limiting carbon source in the absence of kanamycin. The Tn5-bearing strain has a more rapid growth rate and increases in frequency from 50% to 90% within the first 15 to 20 generations. The effect occurs when Tn5 is inserted at a ...
متن کاملProtein ProQ influences osmotic activation of compatible solute transporter ProP in Escherichia coli K-12.
ProP is an osmoregulatory compatible solute transporter in Escherichia coli K-12. Mutation proQ220::Tn5 decreased the rate constant for and the extent of ProP activation by an osmotic upshift but did not alter proP transcription or the ProP protein level. Allele proQ220::Tn5 was isolated, and the proQ sequence was determined. Locus proQ is upstream from prc (tsp) at 41.2 centisomes on the genet...
