Cofactor	COFACTOR: Name=Mg(2+); Xref=ChEBI:CHEBI:18420; Evidence={ECO:0000250|UniProtKB:Q97TX9}; Name=Mn(2+); Xref=ChEBI:CHEBI:29035; Evidence={ECO:0000250|UniProtKB:Q97TX9}; Name=Cu(2+); Xref=ChEBI:CHEBI:29036; Evidence={ECO:0000250|UniProtKB:Q97TX9}; Note=Mg(2+) or Mn(2+) required for ssDNA cleavage activity. Can also utilise Cu(2+). {ECO:0000250|UniProtKB:Q97TX9}; COFACTOR: Name=[4Fe-4S] cluster; Xref=ChEBI:CHEBI:49883; Evidence={ECO:0000250|UniProtKB:Q97TX9}; Note=Binds 1 [4Fe-4S] cluster per subunit. It may be important for protein stability, since mutation of the Cys that bind the cofactor leads to a colorless, insoluble protein. {ECO:0000250|UniProtKB:Q97TX9};
