EcoRI and EcoRV have a very similar active site, as is apparent from a comparison of the structures of their respective protein-DNA complexes. Based on structural and mechanistic data, as well as detailed molecular modelling presented here, a mechanism for the DNA cleavage by these enzymes is suggested in which the attacking water molecule is activated by the phosphate group 3' to the scissile phosphodiester bond, and in which the leaving group is protonated by a water molecule associated with the essential cofactor, Mg2+. The mechanism proposed may also apply to other nucleases.
