| Description |
An enzyme from Leishmania donovani that decatenates kinetoplast DNA networks into covalently closed monomeric circles
has been isolated and characterized. The enzyme also relaxes supercoiled plasmid pBR322. The decatenation and relaxation reactions
both require ATP and Mg 2-. In both reactions the formation of topological isomers of unique linking numbers suggests
that the enzyme is a type II DNA topoisomerase. Both the relaxation and decatenating activities are inhibited by novobiocin at
a very high concentration
