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:0000256|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:0000256|HAMAP-
CC Rule:MF_00034};
CC -!- COFACTOR:
CC Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC Evidence={ECO:0000256|HAMAP-Rule:MF_00034};
CC Note=Binds 2 Mg(2+) ion per subunit. {ECO:0000256|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:0000256|HAMAP-Rule:MF_00034}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000256|HAMAP-Rule:MF_00034}.
CC -!- SIMILARITY: Belongs to the RuvC family. {ECO:0000256|ARBA:ARBA00009518,
CC ECO:0000256|HAMAP-Rule:MF_00034}.
