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. WebMany restriction enzymes are sensitive to the DNA methylation states. Cleavage may be blocked, or impaired, when a particular base in the enzyme's recognition site is modified. Methylation sensitive restriction …

WebDam methylase recognizes GATC and attaches a methyl group to the adenine base of both strands prior to replication. After replication, though, only the parental strand is methylated, thus, the DNA is hemi-methylated. Any erroneous base inserted during replication is recognized by the mismatch repair enzymes.
