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. WebThis enzyme is blocked by dam methylation. More information can be found at Dam-Dcm and CpG Methylation. For enzymes that cannot be heat-inactivated, we recommend …
