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}.
