Temperature dependence of sex-factor maintenance in Escherichia coli K-12.
نویسندگان
چکیده
Wild-type sex factors of Escherichia coli K-12 can be cured from host cells by growth at temperatures above 42 C. This phenomenon is obscured by reinfection of cured cells if the culture is allowed to reach cell densities above 10(5)/ml. The rate of episome loss is dependent on the genetic (chromosomal) background of the host.

Bacteriol. 91:1767-1772. 1966.-The sex factor of Escherichia coli K-12 was introduced into an E. coli B/r strain by circumventing the host-controlled modification and restriction incompatibilities known to exist between these closely related strains. The sexual properties of the constructed F(+) B strain and...
متن کاملTemperature-sensitive mutants for the replication of plasmids in Escherichia coli. I. Isolation and specificity of host and plasmid mutations.
Temperature-sensitive mutants of Escherichia coli defective in the replication of the plasmid colicinogenic factor E1 (ColE(1)) were isolated following mutagenesis of E. coli K12 strain carrying the ColE(1) factor. Following the mutagenic treatment an enrichment procedure utilizing the replacement of thymine with bromouracil in the ColE(1) DNA duplicated at the restrictive temperature was used....
متن کاملThe Expression of Human Granulocyte Macrophage Colony Stimulating Factor by Heat-Induction in Escherichia coli
A self-regulated high-copy number plasmid containing chloramphenicol resistant gene, for the production of recombinant proteins under the regulation of bacteriophage ?pL promoter, was constructed. The designed 5024 base pair expression plasmid contained a heat sensitive repressor cI857 coding gene to regulate the function of ?pL promoter under heat shock induction. Using the constructed vector,...

With the aim of the secretion of human granulocyte macrophage-colony stimulating factor (hGM-CSF) in Escherichia coli, hGM-CSF cDNA was fused in-frame next to the signal sequence of ST toxin (ST-I) of exteroxigenic E. coli, containing 53 or 19 amino acids of signal peptide. The fused STsig::hGM-CSF coding fragments were inserted into a T7-based expression plasmid. The recombinant plasmids were ...
متن کاملTemperature dependence of MinD oscillation in Escherichia coli: running hot and fast.
We observed that the oscillation period of MinD within rod-like and filamentous cells of Escherichia coli varied by a factor of 4 in the temperature range from 20 degrees C to 40 degrees C. The detailed dependence was Arrhenius, with a slope similar to the overall temperature-dependent growth curve of E. coli. The detailed pattern of oscillation, including the characteristic wavelength in filam...
