Isolation of a Mutant of Escherichia coli Defective in Cytosine-Specific Deoxyribonucleic Acid Methylase Activity and in Partial Protection of Bacteriophage λ Against Restriction by Cells Containing the N-3 Drug-Resistance Factor
A mutant (designated mec(−)) of Escherichia coli F(+) 100 endo I(−)su(+) r(K)(−)m(K)(+) has been isolated which is defective in cytosine-specific deoxyribonucleic acid (DNA) methylase activity. The DNA of this mutant, as well as the DNA of phages λ and fd propagated in it, is virtually devoid of 5-m...
