Term Name: EC 5.99.1.2 (DNA topoisomerase) inhibitor
Synonyms: DNA topoisomerase inhibitor, DNA topoisomerase inhibitors, EC 5.99.1.2 (DNA topoisomerase) inhibitors, EC 5.99.1.2 (topoisomerase I) inhibitor, EC 5.99.1.2 (topoisomerase I) inhibitors, EC 5.99.1.2 inhibitor, EC 5.99.1.2 inhibitors, topoisomerase I (EC 5.99.1.2) inhibitor, topoisomerase I (EC 5.99.1.2) inhibitors, topoisomerase I inhibitor, topoisomerase I inhibitors, type I DNA topoisomerase inhibitor, type I DNA topoisomerase inhibitors
Definition: A topoisomerase inhibitor that inhibits the bacterial enzymes of the DNA topoisomerases, Type I class (EC 5.99.1.2) that catalyze ATP-independent breakage of one of the two strands of DNA, passage of the unbroken strand through the break, and rejoining of the broken strand. These bacterial enzymes reduce the topological stress in the DNA structure by relaxing negatively, but not positively, supercoiled DNA.
