Subunit assembly modulates the activities of the Type III restriction–modification enzyme PstII in vitro

We demonstrate that, like other Type III restriction endonuclease, PstII does not turnover such that a DNA substrate is only fully cleaved at a Res(2)Mod(2)-to-site ratio of ∼1:1. However, unlike other Type III enzymes, the cleavage rate profiles varied with protein concentration: using 5 nM DNA and...
