CC -!- FUNCTION: Modifies the topological state of DNA by introducing positive CC supercoils in an ATP-dependent process, increasing the linking number CC in steps of +1. Binds to single-stranded DNA, transiently cleaves and CC then rejoins the ends, introducing a positive supercoil in the process. CC The scissile phosphodiester is attacked by the catalytic tyrosine of CC the enzyme, resulting in the formation of a DNA-(5'-phosphotyrosyl)- CC enzyme intermediate. Involved in rewinding DNA strands in regions of CC the chromosome that have opened up to allow replication, transcription, CC DNA repair and/or for DNA protection. {ECO:0000256|RuleBase:RU004026}.

CC {ECO:0000256|HAMAP-Rule:MF_01125}. CC -!- CATALYTIC ACTIVITY: CC Reaction=ATP + H2O = ADP + H(+) + phosphate; Xref=Rhea:RHEA:13065, CC ChEBI:CHEBI:15377, ChEBI:CHEBI:15378, ChEBI:CHEBI:30616, CC ChEBI:CHEBI:43474, ChEBI:CHEBI:456216; CC Evidence={ECO:0000256|ARBA:ARBA00001836, ECO:0000256|HAMAP- CC Rule:MF_01125, ECO:0000256|RuleBase:RU004026}; CC -!- COFACTOR: CC Name=Mg(2+); Xref=ChEBI:CHEBI:18420; CC Evidence={ECO:0000256|ARBA:ARBA00001946}; CC -!- COFACTOR: CC Name=Zn(2+); Xref=ChEBI:CHEBI:29105; CC Evidence={ECO:0000256|HAMAP-Rule:MF_01125}; CC Note=Binds 1 or 2 zinc ions per subunit. {ECO:0000256|HAMAP- CC Rule:MF_01125}; CC -!- SUBUNIT: Monomer. {ECO:0000256|HAMAP-Rule:MF_01125}. CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000256|ARBA:ARBA00004496, CC ECO:0000256|HAMAP-Rule:MF_01125}. CC -!- DOMAIN: Introduction of positive supercoils requires the cooperation of CC both domains. The helicase-like domain probably does not directly CC unwind DNA, but more likely acts by driving ATP-dependent CC conformational changes within the whole enzyme. A beta hairpin in the CC 'latch' region of the N-terminal domain plays a regulatory role in the CC enzyme, repressing topoisomerase activity in the absence of ATP and CC preventing the enzyme from acting as an ATP-independent relaxing CC enzyme; it also helps to coordinate nucleotide hydrolysis by the ATPase CC domain with the supercoiling activity of the topoisomerase domain. CC {ECO:0000256|HAMAP-Rule:MF_01125}. CC -!- MISCELLANEOUS: This enzyme is the only unique feature of CC hyperthermophilic bacteria/archaea known and seems to be essential for CC adaptation to life at high temperatures. It may play a role in CC stabilization of DNA at high temperatures. {ECO:0000256|HAMAP- CC Rule:MF_01125}. CC -!- SIMILARITY: In the C-terminal section; belongs to the type IA CC topoisomerase family. {ECO:0000256|HAMAP-Rule:MF_01125}. CC -!- SIMILARITY: In the N-terminal section; belongs to the DEAD box helicase CC family. DDVD subfamily. {ECO:0000256|ARBA:ARBA00043976, CC ECO:0000256|HAMAP-Rule:MF_01125}.
