[Effect of insertional mutation in the cspA gene encoding the major cold-shock protein on radiation resistance of Escherichia coli].

Abstract excerpt

Plasmid pCspA::Km carrying a cloned mutant allele of the cspA gene for the major Escherichia coli cold-shock protein CspA with an insertion of the kanamycin resistance gene cassette from transposon Tn903 into the core region of the coding sequence causes a 2.3-fold increase in radioresistance of wild-type E. coli cells (cspA+). The radioprotective effect of this plasmid is abolished or drastically reduced in...
