General annotation (Comments)

Function	The RuvA-RuvB complex in the presence of ATP renatures cruciform structure in supercoiled DNA with palindromic sequence, indicating that it may promote strand exchange reactions in homologous recombination. RuvAB is an helicase that mediates the Holliday junction migration by localized denaturation and reannealing. RuvA stimulates, in the presence of DNA, the weak ATPase activity of RuvB. Binds both single- and double-stranded DNA (dsDNA). Binds preferentially to supercoiled rather than to relaxed dsDNA. HAMAP MF_00031
Catalytic activity	ATP + H2O = ADP + phosphate. HAMAP MF_00031
Subunit structure	Homotetramer; forms a complex with RuvB.
Induction	Expression of the ruv region is induced by damage to DNA and is regulated by LexA as part of the SOS response. RuvA and RuvB are also involved in mutagenesis induced by UV and X irradiation and by some chemicals. HAMAP MF_00031
Sequence similarities	Belongs to the RuvA family.
