Spasmolytic 1321 Topoisomerase-I inhibitor 1368 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. Topoisomerase-II inhibitor 1366 A topoisomerase inhibitor that inhibits DNA topoisomerase (ATP-hydrolysing), EC 5.99.1.3 (topoisomerase II), which catalyses ATP-dependent breakage of both strands of DNA, passage of the unbroken strands through the breaks, and rejoining of the broken strands.
