CC   -!- FUNCTION: The RuvA-RuvB-RuvC complex processes Holliday junction (HJ)
CC       DNA during genetic recombination and DNA repair. Endonuclease that
CC       resolves HJ intermediates. Cleaves cruciform DNA by making single-
CC       stranded nicks across the HJ at symmetrical positions within the
CC       homologous arms, yielding a 5'-phosphate and a 3'-hydroxyl group;
CC       requires a central core of homology in the junction. The consensus
CC       cleavage sequence is 5'-(A/T)TT(C/G)-3'. Cleavage occurs on the 3'-side
CC       of the TT dinucleotide at the point of strand exchange. HJ branch
CC       migration catalyzed by RuvA-RuvB allows RuvC to scan DNA until it finds
CC       its consensus sequence, where it cleaves and resolves the cruciform
CC       DNA. {ECO:0000255|HAMAP-Rule:MF_00034}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=Endonucleolytic cleavage at a junction such as a reciprocal
CC         single-stranded crossover between two homologous DNA duplexes
CC         (Holliday junction).; EC=3.1.21.10; Evidence={ECO:0000255|HAMAP-
CC         Rule:MF_00034};
CC   -!- COFACTOR:
CC       Name=Mg(2+); Xref=ChEBI:CHEBI:18420; Evidence={ECO:0000255|HAMAP-
CC         Rule:MF_00034};
CC       Note=Binds 2 Mg(2+) ion per subunit. {ECO:0000255|HAMAP-Rule:MF_00034};
CC   -!- SUBUNIT: Homodimer which binds Holliday junction (HJ) DNA. The HJ
CC       becomes 2-fold symmetrical on binding to RuvC with unstacked arms; it
CC       has a different conformation from HJ DNA in complex with RuvA. In the
CC       full resolvosome a probable DNA-RuvA(4)-RuvB(12)-RuvC(2) complex forms
CC       which resolves the HJ. {ECO:0000255|HAMAP-Rule:MF_00034}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_00034}.
CC   -!- SIMILARITY: Belongs to the RuvC family. {ECO:0000255|HAMAP-
CC       Rule:MF_00034}.
