CC -!- FUNCTION: Releases the supercoiling and torsional tension of DNA
CC introduced during the DNA replication and transcription by transiently
CC cleaving and rejoining one strand of the DNA duplex. Introduces a
CC single-strand break via transesterification at the specific target site
CC 5'-[CT]CCTTp site in duplex DNA. The scissile phosphodiester is
CC attacked by the catalytic tyrosine of the enzyme, resulting in the
CC formation of a DNA-(3'-phosphotyrosyl)-enzyme intermediate and the
CC expulsion of a 5'-OH DNA strand. The free DNA strand then undergoes
CC passage around the unbroken strand thus removing DNA supercoils.
CC Finally, in the religation step, the DNA 5'-OH attacks the covalent
CC intermediate to expel the active-site tyrosine and restore the DNA
CC phosphodiester backbone. {ECO:0000256|RuleBase:RU365101}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=ATP-independent breakage of single-stranded DNA, followed by
CC passage and rejoining.; EC=5.6.2.1;
CC Evidence={ECO:0000256|ARBA:ARBA00000213,
CC ECO:0000256|RuleBase:RU365101};
CC -!- SIMILARITY: Belongs to the type IB topoisomerase family.
