Topoisomer

From Biocrawler, the free encyclopedia.

Topoisomers or topological isomers are molecules with the same chemical formula but different topologies. Examples of molecules for which there exist topoisomers include DNA, which can form knots, and catenanes. DNA topoisomers can be interchanged by enzymes called topoisomerases.
