Structure, Molecular Mechanisms, and Evolutionary Relationships in DNA Topoisomerases
2004
Annual Review of Biophysics and Biomolecular Structure
■ Abstract Topoisomerases are enzymes that use DNA strand scission, manipulation, and rejoining activities to directly modulate DNA topology. These actions provide a powerful means to effect changes in DNA supercoiling levels, and allow some topoisomerases to both unknot and decatenate chromosomes. Since their initial discovery over three decades ago, researchers have amassed a rich store of information on the cellular roles and regulation of topoisomerases, and have delineated general models
