Chain A,B   (O50390_MYCTO | O50390)
molecular function
    GO:0008657    DNA topoisomerase (ATP-hydrolyzing) inhibitor activity    Stops, prevents or reduces the activity of ATP-hydrolyzing DNA topoisomerase. ATP-hydrolyzing DNA topoisomerase catalyzes the DNA topological transformation by transiently cleaving a pair of complementary DNA strands to form a gate through which a second double-stranded DNA segment is passed, after which the severed strands in the first DNA segment are rejoined; product release is coupled to ATP binding and hydrolysis; changes the linking number in multiples of 2.
    GO:0042803    protein homodimerization activity    Interacting selectively and non-covalently with an identical protein to form a homodimer.
biological process
    GO:2000372    negative regulation of DNA topoisomerase (ATP-hydrolyzing) activity    Any process that stops, prevents or reduces the frequency, rate or extent of DNA topoisomerase (ATP-hydrolyzing) activity.
    GO:0046677    response to antibiotic    Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of an antibiotic stimulus. An antibiotic is a chemical substance produced by a microorganism which has the capacity to inhibit the growth of or to kill other microorganisms.
