Two Restriction and Modification Systems in Staphylococcus aureusnctc8325 (original) (raw)

Abstract

SUMMARY: The presence of two distinct host specificities in Staphylococcus aureus strain nctc8325 was revealed by the isolation of restriction- and modification-deficient mutants. The two host specificity systems, designated S1 and S2, are both active on phage 80μ α but are not additive in their restricting activity. Restriction-deficient, modification-proficient mutants were invariably affected in both restriction systems. The functional relationship between these two systems is discussed.
