Crystal structure of a bacterial topoisomerase IB in complex with DNA reveals a secondary DNA binding site
Type IB DNA topoisomerases (TopIB) are enzymes that relax supercoils by cleaving and resealing one strand of duplex DNA within a protein clamp that embraces a DNA segment. A longstanding conundrum concerns the capacity of TopIB enzymes to stabilize intramolecular duplex DNA crossovers and, in the ca...
