Roles Classification
Biological Roles:
EC 5.99.1.3 [DNA topoisomerase (ATP-hydrolysing)] inhibitor  A topoisomerase inhibitor that inhibits DNA topoisomerase (ATP-hydrolysing), EC 5.99.1.3 (also known as topoisomerase II and as DNA gyrase), which catalyses ATP-dependent breakage of both strands of DNA, passage of the unbroken strands through the breaks, and rejoining of the broken strands.
metabolite  Any intermediate or product resulting from metabolism. The term 'metabolite' subsumes the classes commonly known as primary and secondary metabolites.
