RuvA specifically binds to HJ cruciform DNA, conferring on it an open structure. The RuvB hexamer acts as an ATP-dependent pump, pulling dsDNA into and through the RuvAB complex. HJ branch migration allows RuvC to scan DNA until it finds its consensus sequence, where it cleaves and resolves the cruciform DNA (By similarity). Complements an E.coli deletion mutant (PubMed:8982068).[HAMAP-Rule:MF_00031]
