Type I restriction enzymes possess three subunits called HsdR, HsdM, and HsdS ; HsdR is required for restriction ; HsdM is necessary for adding methyl groups to host DNA ( methyltransferase activity ) and HsdS is important for specificity of the recognition ( DNA-binding ) site in addition to both restriction ( DNA cleavage ) and modification ( DNA methyltransferase ) activity.
