CC -!- FUNCTION: Introduces a single-strand break via transesterification at a
CC target site in duplex DNA. Releases the supercoiling and torsional
CC tension of DNA introduced during the DNA replication and transcription
CC by transiently cleaving and rejoining one strand of the DNA duplex. The
CC scissile phosphodiester is attacked by the catalytic tyrosine of the
CC enzyme, resulting in the formation of a DNA-(5'-phosphotyrosyl)-enzyme
CC intermediate and the expulsion of a 3'-OH DNA strand.
CC {ECO:0000256|RuleBase:RU362092}.
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:RU362092};
CC -!- SIMILARITY: Belongs to the type IA topoisomerase family.
CC {ECO:0000256|ARBA:ARBA00009446, ECO:0000256|RuleBase:RU362092}.
