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}.
