General annotation (Comments)

Function	Releases the supercoiling and torsional tension of DNA introduced during the DNA replication and transcription by transiently cleaving and rejoining one strand of the DNA duplex. 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 than 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 By similarity. SAAS SAAS000380
Catalytic activity	ATP-independent breakage of single-stranded DNA, followed by passage and rejoining. RuleBase RU000518 SAAS SAAS005733
Sequence similarities	Belongs to the prokaryotic type I/III topoisomerase family. RuleBase RU004206 Contains 1 Toprim domain. SAAS SAAS023406
