Fig. 7. Substrate specificity of recombinant CuquEndo-containing supernatant on different single- or double-stranded polynucleotides. Hydrolysis products were resolved using an IEC-DEAE-NPR column. Recombinant CuquEndo hydrolyzed only double-stranded DNA with no sequence specificity. No endonuclease activity was detected on single-stranded substrates.
