RC STRAIN=DSM 14826 {ECO:0000313|Proteomes:UP000243547}; RA Varghese N., Submissions S.; RL Submitted (NOV-2016) to the EMBL/GenBank/DDBJ databases. 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:0000256|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; CC Evidence={ECO:0000256|ARBA:ARBA00029354, 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 1 Mg(2+) ion per subunit. {ECO:0000256|HAMAP-Rule:MF_00034}; CC -!- SIMILARITY: Belongs to the RuvC family. {ECO:0000256|ARBA:ARBA00009518, CC ECO:0000256|HAMAP-Rule:MF_00034}.
