Abstract
An enzyme from Leishmaniadonovani that catenates monomeric pBR322 into huge catenanes has been isolated and characterized. The enzyme also decatenates kinetoplast DNA networks into covalently closed monomeric circles and relaxes supercoiled pBR322. The catenation, decatenation and relaxation reactions do not require ATP. The formation of topological isomers of unique linking numbers suggest that the enzyme is a type II DNA topoisomerase.
