Function

function

The RuvA-RuvB-RuvC complex processes Holliday junction (HJ) DNA during genetic recombination and DNA repair, while the RuvA-RuvB complex plays an important role in the rescue of blocked DNA replication forks via replication fork reversal (RFR). 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.

Caution

Lacks conserved residue(s) required for the propagation of feature annotation.

Interaction

Subunit

Homotetramer. Forms an RuvA8-RuvB12-Holliday junction (HJ) complex. HJ DNA is sandwiched between 2 RuvA tetramers; dsDNA enters through RuvA and exits via RuvB. An RuvB hexamer assembles on each DNA strand where it exits the tetramer. Each RuvB hexamer is contacted by two RuvA subunits (via domain III) on 2 adjacent RuvB subunits; this complex drives branch migration. In the full resolvosome a probable DNA-RuvA4-RuvB12-RuvC2 complex forms which resolves the HJ.
