WebJan 6, 2014 · Although the EcoRI enzyme recognizing GAATTC is used as an enzyme that is not sensitive to methylation in MSAP, EcoRI did not digest GAATTmC sequences when cytosines at both strands are methylated [34, 35].Thus, EcoRI digestion may be inhibited by overlapping C methylation, indicating that not all changes in MH patterns always reflect … WebJun 5, 1988 · In the product of EcoRI enzymatic methylation, all of the isotope remains at the N6 position of the N6-methyladenine product. It is concluded that, contrary to existing chemical precedent, the methylation occurs by direct transfer from S-adenosylmethionine to the N6 of adenine in DNA.
