SUMMARY: The genetic properties of a new () host specificity of were investigated using bacteriophage L. Phage L is a better substrate for s-specific restriction than phage P22. Mutants deficient in s-restriction only were found at the same frequency as mutants deficient in both restriction and modification. Crosses between Hfr and F or between and showed that the s system has the same chromosomal location as the K system of The s system was introduced into and found to be effective on phage λ.
