Dam methylation restriction enzymes
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 … DNA adenine methylase, (Dam methylase) (also site-specific DNA-methyltransferase (adenine-specific), EC 2.1.1.72, modification methylase, restriction-modification system) is an enzyme that adds a methyl group to the adenine of the sequence 5'-GATC-3' in newly synthesized DNA. Immediately after DNA synthesis, the daughter strand remains unmethylated for a short ti…
