title: [A method for detecting new strains producing DNA modification and restriction enzymes--isoschizomers and isomethylomers of known restrictases and methylases].
abstract: The paper describes a technique for the detection of new strains producing enzymes which mediate DNA modification and restriction, and isoschizomers and isomethylomers of the known restriction endonucleases and methylases. Three Bacillus subtilis strains whose DNA carries a BamH1 modification have been found. Two of these strains exert the restrictase activity with an R BamH1 specificity.
