| 3.1.21.3 | DNA + H2O |
HsdR subunit can produce only a single cleavage of the phosphodiester backbone of the DNA but can cooperate with another HsdR subunit to produce full DNA cleavage, producing DNA with overhanging ends of single-stranded DNA. On a single-site plasmid, cleavage requires the association of HsdR, from solution, to the cleavage complex in order to produce double-strand cleavage |

the wild type enzyme EcoK cleaves circular DNA. Only one endonuclease molecule is required per cleavage event. Cleavage of linear DNA may require a second endonuclease molecule |
