locus-tag	class	description
	COG0817	Nuclease that resolves Holliday junction intermediates in genetic recombination. Cleaves the cruciform structure in supercoiled DNA by nicking to strands with the same polarity at sites symmetrically opposed at the junction in the homologous arms and leaves a 5'-terminal phosphate and a 3'-terminal hydroxyl group
	COG4804	nuclease activity
	COG0666	response to abiotic stimulus
	COG1961	COG1961 Site-specific recombinases, DNA invertase Pin homologs
