  • Title: [Methyl-cytosine specific restriction in Escherichia coli K-12].
    Author: Povilenis PI, Lubis AA, Vaĭshvila RI, Kulakauskas ST, Ianulaĭtis AA.
    Journal: Genetika; 1989 Apr; 25(4):753-5. PubMed ID: 2547699.
    Abstract:
    Experiments on transformation of Escherichia coli K-12 cells by plasmids carrying RM systems with different recognition sites containing 5-methylcytosine have shown that the gene mcrB determines the function of restriction. The data obtained made it possible to believe that E. coli possesses no restriction system recognizing specifically cytosine methylated in position 4.
