title: [Isolation, purification and properties of restriction endonuclease EcoRII].
abstract: The restriction endonuclease Eco RII was isolated and purified to homogeneity. The isolation procedure involved the use of the E. coli strain B834/pSK323, containing the recombinant plasmide pSK323 which provides for the oversynthesis of Eco RII enzymes. Data from gel filtration and Na-DS electrophoresis suggest that the restriction endonuclease Eco RII is a protein made up of two subunits, each with molecular weight of 44 000.
