The regulatory gene (argR) for the arginine biosynthetic pathway has been located at 106 min on the chromosome of S. typhimurium. In addition, the location of the gene specifying cytosine deaminase (cod) has been more precisely determined.
We describe recJ mutants of Salmonella typhimurium. The recJ gene maps between sufD and serA (min 62) and is transcribed counterclockwise. Unlike recJ mutants of Escherichia coli, recJ strains of S. typhimurium are sensitive to irradiation with UV light. This sensitivity is equivalent to or greater
The repressor gene Cll of the L phage was cloned into plasmid pHC624 and expressed in E. coli. Two separate binding affinities for L phage DNA were identified during fractionation of protein extract of that strain. The activity that salts out in low concentration of ammonium sulphate belonged to the
