Introduces a single-strand break via transesterification at a target site in duplex DNA. The scissile phosphodiester is attacked by the catalytic tyrosine of the enzyme, resulting in the formation of a DNA-(5'-phosphotyrosyl)-enzyme intermediate and the expulsion of a 3'-OH DNA strand. The free DNA strand then undergoes passage around the unbroken strand, thus removing DNA supercoils. Finally, in the religation step, the DNA 3'-OH attacks the covalent intermediate to expel the active-site tyrosine and restore the DNA phosphodiester backbone"],"length":775,"sequence":"MQENLVIVESPAKAKTIEKFLGDDYKVMSSYGHIRDLKKKELSINPKTLEPDYEIPDEKKKLVSELKANAKKAKKIWLASDEDREGEAISWHLCEVLGLDEAKTSRIVFHEITKSAILDAIKSPRHLNMNLVNAQQARRVLDRLVGFKLSPVLWRKVKPALSAGRVQSVAVRLIVEREREIQAFHSEPYYRINAVFSITNSDGSQGEVKTELDTRFKTHKEAIDFLEQCKDAKFSVGSITKKPLHRTPAPPFTTSTLQQEAARKLGFTVSQTMMVAQRLYENGHITYMRTDSVNLSSLAINTSKDEIIKLWGKEYSKVRNYHTHSKGAQEAHEAIRPTYMSNTQIDGTAQEKRLYELIWKRTAASQMADALIDKTTITIDIAGSQAKFIANGEVITFDGFLKVYRESTDDEDNNTEETAHILPVMKVGDVLERHEITSTERFSMGPIRYTEASLVHKLEELGIGRPSTYAPTISTIQQREYVQKGDKKGEERTYTIDTLKGTKVMSRERKEMVGNEKGKLLPTDIGIVVNDFLMENFPDIMDYNFTAKVEQQFDQIAEGNEEWNSMMKLFDKSFEPTVDKVMNARSEHKAGERQLGEEPGTGKPVFVKIGRFGPVVQIGSADDAEKPRFSQLPSDKSIETITLDEALELFKLPRTIGEFEGSEVVIGAGRFGPYVMHNKKYVSLPKGTDPMKVTLDEAIQLITEKREQEQKRHIKTFEEDPKLEVLNGRYGPYIAYDGKNYRMPKTLHEKAAELSFEECMNIVNNAPEPKSRKKK","proteome":null,"gene":"topA","go_terms":[{"identifier":"GO:0003677","name":"DNA binding","category":{"code":"F","name":"molecular_function"}},{"identifier":"GO:0003916","name":"DNA topoisomerase activity","category":{"code":"F","name":"molecular_function"}},{"identifier":"GO:0006265","name":"DNA topological change","category":{"code":"P","name":"biological_process"}},{"identifier":"GO:0003917","name":"DNA topoisomerase type I (single strand cut, ATP-independent) activity","category":{"code":"F","name":"molecular_function"}}],"protein_evidence":3,"source_database":"unreviewed","is_fragment":false,"in_alphafold":true,"in_bfvd":false,"ida_accession":"81f540a8b1a39d7dd7bfe15c84072b1098358d52","counters":{"domain_architectures":854,"entries":24,"isoforms":0,"proteomes":0,"sets":3,"structures":0,"taxa":1,"dbEntries":{"smart":3,"profile":2,"cdd":2,"pfam":3,"panther":1,"hamap":1,"ncbifam":1,"prosite":1,"interpro":10},"proteome":0,"taxonomy":1,"similar_proteins":854}}}
