Reverse gyrase binding to DNA alters the double helix structure and produces single-strand cleavage in the absence of ATP.
Stoichiometric amounts of pure reverse gyrase, a type I topoisomerase from the archaebacterium Sulfolobus acidocaldarius were incubated at 75 degrees C with circular DNA containing a single-chain scission. After covalent closure by a thermophilic ligase and removal of bound protein molecules, negati...
