Chain A   (YACG_ECOLI | P0A8H8)
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:0046872    metal ion binding    Interacting selectively and non-covalently with any metal ion.
    GO:0008270    zinc ion binding    Interacting selectively and non-covalently with zinc (Zn) ions.
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:0006355    regulation of transcription, DNA-templated    Any process that modulates the frequency, rate or extent of cellular DNA-templated transcription.
