Identification of contacts between topoisomerase I and its target DNA by site-specific photocrosslinking.
Vaccinia DNA topoisomerase, a eukaryotic type I enzyme, binds and cleaves duplex DNA at sites containing the sequence 5'-(T/C)CCTT. We report the identification of Tyr70 as the site of contact between the enzyme and the +4C base of its target site. This was accomplished by UV-crosslinking topoi...
