CC -!- FUNCTION: The RuvA-RuvB complex in the presence of ATP renatures
CC cruciform structure in supercoiled DNA with palindromic sequence,
CC indicating that it may promote strand exchange reactions in homologous
CC recombination. RuvAB is a helicase that mediates the Holliday junction
CC migration by localized denaturation and reannealing. RuvA stimulates,
CC in the presence of DNA, the weak ATPase activity of RuvB.
CC {ECO:0000255|HAMAP-Rule:MF_00031}.
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; EC=3.6.4.12;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_00031};
CC -!- SUBUNIT: Forms a complex with RuvB. {ECO:0000255|HAMAP-Rule:MF_00031}.
CC -!- SIMILARITY: Belongs to the RuvA family. {ECO:0000255|HAMAP-
CC Rule:MF_00031}.
