Abstract

strain PC-7 carries two independent temperature-sensitive mutations, one affecting the restriction and modification (R-M) phenotype and the other the DnaC(D) phenotype. The results of complementation and P1 transduction analysis of the mutation affecting the R-M phenotype implicate a fourth gene, designated , located close to the three-gene complex. The properties of merodiploids constructed between appropriate recipients and F' elements with different mutations in , and genes might indicate that in strain PC-7 the temperature-sensitive products, determined by and cistrons, are synthesized. The role of the temperature-sensitive () gene product in the formation of the restriction endonuclease was studied and no direct relation was found between the DnaC(D) and R-M phenotypes.
