CC   -!- FUNCTION: Nuclease that resolves Holliday junction intermediates in
CC       genetic recombination. Cleaves the cruciform structure in supercoiled
CC       DNA by nicking to strands with the same polarity at sites symmetrically
CC       opposed at the junction in the homologous arms and leaves a 5'-terminal
CC       phosphate and a 3'-terminal hydroxyl group. {ECO:0000255|HAMAP-
CC       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;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_00034};
CC       Note=Binds 1 Mg(2+) ion per subunit. {ECO:0000255|HAMAP-Rule:MF_00034};
CC   -!- SIMILARITY: Belongs to the RuvC family. {ECO:0000255|HAMAP-
CC       Rule:MF_00034}.
