CC -!- FUNCTION: Releases the supercoiling and torsional tension of DNA, which
CC is introduced during the DNA replication and transcription, by
CC transiently cleaving and rejoining one strand of the DNA duplex.
CC Introduces a single-strand break via transesterification at a target
CC site in duplex DNA. The scissile phosphodiester is attacked by the
CC catalytic tyrosine of the enzyme, resulting in the formation of a DNA-
CC (5'-phosphotyrosyl)-enzyme intermediate and the expulsion of a 3'-OH
CC DNA strand. The free DNA strand then undergoes passage around the
CC unbroken strand, thus removing DNA supercoils. Finally, in the
CC religation step, the DNA 3'-OH attacks the covalent intermediate to
CC expel the active-site tyrosine and restore the DNA phosphodiester
CC backbone. {ECO:0000256|HAMAP-Rule:MF_00952}.
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, ECO:0000256|HAMAP-
CC Rule:MF_00952};
CC -!- SUBUNIT: Monomer. {ECO:0000256|HAMAP-Rule:MF_00952}.
CC -!- SIMILARITY: Belongs to the type IA topoisomerase family.
CC {ECO:0000256|ARBA:ARBA00009446, ECO:0000256|HAMAP-Rule:MF_00952}.
CC -!- CAUTION: Lacks conserved residue(s) required for the propagation of
CC feature annotation. {ECO:0000256|HAMAP-Rule:MF_00952}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
