- Аннотация: The present study deals with the binding and cleavage by EcoRII endonuclease of concatemer DNA duplexes containing EcoRII recognition sites (formula; see text) in which dT is replaced by dU or 5-bromodeoxyuridine, or 5'-terminal dC in the dT-containing strand is methylated at position 5. The enzyme molecule is found to interact with the methyl group of the dT residue of the DNA recognition site and to be at least in proximity to the H5 atom of the 5'-terminal dC residue in dT-containing strand of this site. Modification of any of these positions exerts an equal effects on the cleavage of both DNA strands. Endonuclease EcoRII was found to bind the substrate specifically. At the same time modification of the bases in recognized sequence may result in the formation of unproductive, though stable, enzyme-substrate complexes.
