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 a 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 By similarity. HAMAP-Rule MF_00031
Catalytic activity	ATP + H2O = ADP + phosphate. HAMAP-Rule MF_00031
Subunit structure	Forms a complex with RuvB By similarity.
Sequence similarities	Belongs to the RuvA family.
