Resolvase complexed with DNA. Molecular model of RusA resolvase (purple and green) bound to a DNA (deoxyribonucleic acid, pink and orange) duplex. Resolvase enzymes take part in genetic recombination, where DNA strands combine, split and mix, redistributing genetic information. RusA cleaves four-way DNA junctions by creating symmetrical cuts in the DNA backbone.
