Partial purification of the Escherichia coli K-12 mec+ deoxyribonucleic acid-cytosine methylase: in vitro methylation completely protects bacteriophage lambda deoxyribonucleic acid against cleavage by R-EcoRII.
A procedure is described for the partial purification of the deoxyribonucleic acid (DNA)-cytosine methylases controlled by the RII plasmid and by the Escherichia coli mec+ gene. The two enzymes exhibit similar but distinct chromatographic behavior on diethylaminoethyl-cellulose and phosphocellulose....
