Endonuclease assay for DNA cleavage by MSFusion. Final concentration of DNA (unmethylated pBRsk1) was 3 nM. Final concentration of reconstituted nuclease was 60 nM using at least 2 HsdR and 1 HsdM per M1S1 protein or MSFusion protein. The enzymes were reconstituted at 1000 nM and then diluted into the solution containing DNA. M = 1 kb ladder; OC = open circle; L = linear; CCC = covalent closed circle.
