Because these enzymes can be custom-built to recognize specific sequences in single-stranded DNA, they hold promise as diagnostic tools or targeted therapeutics\u2014especially in addressing fast-evolving viral infections.<\/p>\n\n\n\n<p>&nbsp;\u201cUnderstanding and optimizing DNA enzymes could lead to precise interventions against single-stranded DNA viruses,\u201d said Ouelett.<\/p>\n\n\n\n<p>Ouelett cites the highly contagious canine parvovirus (CPV) as a possibility for practical deployment of the tool. \u201cIt\u2019s very, very infectious. The treatment is usually euthanasia so that it does not propagate to other dogs.\u201d<\/p>\n\n\n\n<p>He hypothesizes that enzymes like I-R3 could provide a treatment for dogs infected with CPV. \u201cCutting the viral DNA in half would inactivate it: no more virus!\u201d<\/p>\n\n\n\n<p>The study was conducted in collaboration with researchers from Concordia University\u2019s Department of Biology and Center for Applied Synthetic Biology in Montreal and Dalhousie University\u2019s Faculty of Computer Science in Halifax.
