DNAase I footprinting of restriction enzymes.
DNAase I footprinting of restriction enzymes has been achieved by using calcium containing digestion buffers so that the enzymes bind to but do not cleave DNA. EcoR1 produces a footprint 17 bases long, overestimating the region of contact with DNA by about 7-8 base pairs. Restriction enzymes HaeIII and HinP1 generate smaller footprints of 15 and 13 base pairs respectively.
