Comparison of the substrate specificity of GlaI recombinant site-specific methyl-directed DNA endonuclease and the native enzyme isolated from Glacial ice bacterium strain
cloning of GlaI site-specific methyl-directed DNA endonuclease gene and the comparison of the substrate specificity of recombinant and native enzymes is described. The analysis of recombinant GlaI endonuclease properties showed that the substrate specificity of native and recombinant enzymes didn't differ, but the concentration of recombinant enzyme exceeded 10 times of native enzyme
