Mechanism and Specificity of DNA Strand Exchange Catalyzed by Vaccinia DNA Topoisomerase Type I

The type I DNA topoisomerase from vaccinia virus (vTopo) forms a reversible covalent 3′-phosphotyrosyl linkage with a single strand of duplex DNA at the preferred sequence 5′-(C/T)CCTTp↓N(−1)N(−2)N(−3)-3′. The enzyme-DNA covalent adduct is recombinogenic in cells, because the nicked strand downstrea...
