WebNote: Restriction enzyme cleavage is blocked when the recognition sequence is methylated by the cognate methylase. Methylation at other bases can block cleavage, leave cleavage unaffected or slow the rate or extent of cleavage. The rate of cleavage may also be affected by the DNA sequence flanking the recognition site. WebMost restriction enzymes are sensitive to DNA methylation. In cases where a restriction enzyme target site overlaps a methylation site, the following digestion results are …
