<p>The gp41 and Dda helicases were found to significantly enhance the dissociation rate of streptavidin from biotin-labeled oligonucleotides in an ATP dependent reaction, demonstrating that these enzymes are capable of imparting a significant force on a molecule blocking their path. The present invention describes an assay for studying enzymatic activity of a helicase using the rate of dissociation of streptavidin from biotinylated oligonucleotides.</p> |
