Transformation of Escherichia coli with a large plasmid of Acidiphilium multivorum AIU 301 encoding arsenic resistance.

Acidiphilium multivorum AIU 301 isolated from acid mineral water had strong arsenic resistance. This bacterium harbored a number of plasmids with different molecular sizes. A plasmid of 56 kbp, named pKW301, was isolated from A. multivorum AIU 301. When pKW301 was transferred into Escherichia coli JM109 by electroporation, an E. coli transformant carrying pKW301 exhibited resistance to sodium a...

Expression and regulation of the arsenic resistance operon of Acidiphilium multivorum AIU 301 plasmid pKW301 in Escherichia coli.

The arsenic resistance (ars) operon from plasmid pKW301 of Acidiphilium multivorum AIU 301 was cloned and sequenced. This DNA sequence contains five genes in the following order: arsR, arsD, arsA, arsB, arsC. The predicted amino acid sequences of all of the gene products are homologous to the amino acid sequences of the ars gene products of Escherichia coli plasmid R773 and IncN plasmid R46. Th...

Metal resistance in Acidocella strains and plasmid-mediated transfer of this characteristic to Acidiphilium multivorum and Escherichia coli.

Acidophilic heterotrophic strain GS19h of the genus Acidocella exhibited extremely high resistance to CdSO4 and ZnSO4, with a MIC of 1 M for each. The respective MICs for an Acidocella aminolytica strain were 400 and 600 mM. The MICs of NiSO4 for the above strains were 200 and 175 mM, respectively. These strains were also resistant to CuSO4, the MICs being 20 and 40 mM, respectively. An Acidoce...

Natural plasmid transformation in Escherichia coli.

Although Escherichia coli does not have a natural transformation process, strains of E. coli can incorporate extracellular plasmids into cytoplasm 'naturally' at low frequencies. A standard method was developed in which stationary phase cells were concentrated, mixed with plasmids, and then plated on agar plates with nutrients which allowed cells to grow. Transformed cells could then be selecte...

Transformation of Pseudomonas putida and Escherichia coli with plasmid-linked drug-resistance factor DNA.

Conditions optimal for the transformation of Pseudomonas putida and E. coli with a drug-resistance factor (RP 1) DNA, which specifies resistance to carbenicillin, tetracycline, kanamycin, and neomycin, are described. The transformants retain all the fertility, incompatibility, and drug-resistance characteristics present in the parent. Covalently-closed circular molecules of almost identical con...
