== Function ==
[https://www.uniprot.org/uniprot/HJE_SACS2 HJE_SACS2] A structure-specific endonuclease that resolves Holliday junction (HJ) intermediates during genetic recombination. Acts only on 4-way DNA junctions in a sequence non-specific manner; introduces paired nicks in opposing strands 2 bases 3' of the point of strand exchange only on continuous strands of 4-way junction DNA. Cleaves both mobile and immobile junctions.<ref>PMID:10623519</ref> <ref>PMID:10736227</ref> <ref>PMID:15921693</ref>
