CC -!- FUNCTION: The RuvA-RuvB-RuvC complex processes Holliday junction (HJ)
CC DNA during genetic recombination and DNA repair, while the RuvA-RuvB
CC complex plays an important role in the rescue of blocked DNA
CC replication forks via replication fork reversal (RFR). RuvA
CC specifically binds to HJ cruciform DNA, conferring on it an open
CC structure. The RuvB hexamer acts as an ATP-dependent pump, pulling
CC dsDNA into and through the RuvAB complex. RuvB forms 2 homohexamers on
CC either side of HJ DNA bound by 1 or 2 RuvA tetramers; 4 subunits per
CC hexamer contact DNA at a time. Coordinated motions by a converter
CC formed by DNA-disengaged RuvB subunits stimulates ATP hydrolysis and
CC nucleotide exchange. Immobilization of the converter enables RuvB to
CC convert the ATP-contained energy into a lever motion, pulling 2
CC nucleotides of DNA out of the RuvA tetramer per ATP hydrolyzed, thus
CC driving DNA branch migration. The RuvB motors rotate together with the
CC DNA substrate, which together with the progressing nucleotide cycle
CC form the mechanistic basis for DNA recombination by continuous HJ
CC branch migration. Branch migration allows RuvC to scan DNA until it
CC finds its consensus sequence, where it cleaves and resolves cruciform
CC DNA. {ECO:0000256|HAMAP-Rule:MF_00016}.

CC Rule:MF_00016};
CC -!- SUBUNIT: Homohexamer. Forms an RuvA(8)-RuvB(12)-Holliday junction (HJ)
CC complex. HJ DNA is sandwiched between 2 RuvA tetramers; dsDNA enters
CC through RuvA and exits via RuvB. An RuvB hexamer assembles on each DNA
CC strand where it exits the tetramer. Each RuvB hexamer is contacted by
CC two RuvA subunits (via domain III) on 2 adjacent RuvB subunits; this
CC complex drives branch migration. In the full resolvosome a probable
CC DNA-RuvA(4)-RuvB(12)-RuvC(2) complex forms which resolves the HJ.
CC {ECO:0000256|HAMAP-Rule:MF_00016}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000256|HAMAP-Rule:MF_00016}.
CC -!- DOMAIN: Has 3 domains, the large (RuvB-L) and small ATPase (RuvB-S)
CC domains and the C-terminal head (RuvB-H) domain. The head domain binds
CC DNA, while the ATPase domains jointly bind ATP, ADP or are empty
CC depending on the state of the subunit in the translocation cycle.
CC During a single DNA translocation step the structure of each domain
CC remains the same, but their relative positions change.
CC {ECO:0000256|HAMAP-Rule:MF_00016}.
CC -!- SIMILARITY: Belongs to the RuvB family. {ECO:0000256|HAMAP-
CC Rule:MF_00016}.
CC -!- CAUTION: Lacks conserved residue(s) required for the propagation of
CC feature annotation. {ECO:0000256|HAMAP-Rule:MF_00016}.
