Temperature is one of the key environmental parameters affecting bacterial gene expression. This study investigated the effect of… Expand The bactericidal action of colicins K, E1, Ia, and other functionally related colicins involves disruption of active transport… Expand We isolated a colicin K-insensitive energy uncoupled mutant of Escherichia coli. This mutant was presumed to be an ecf mutant as… Expand The rate of colicin K adsorption to Escherichia coli, and consequent death of the bacteria, is progressively inhibited with… Expand Colicin K greatly decreased the incorporation of 32P-labeled inorganic orthophosphate into nucleotides and nucleic acids, causing… Expand The bacterial protein colicin K, when added to sensitive Escherichia coli in the presence of 3,3'-dihexyloxacarbocyanine, cuases… Expand Escherichia coli B, induced for beta-galactoside permease, can accumulate thio-methyl-beta-galactoside in the cell even at 0… Expand The temperature dependence of an early phase of colicin K action was studied. At temperatures of 10 C or lower, colicin K… Expand Cells refractory to the lethal effect of colicin K were selected from a sensitive Escherichia coli K-12 strain. They could still… Expand Partially purified colicin K (mCol K) has been obtained from cultures of Escherichia coli K235 induced with mitomycin C. Unlike… Expand
