Figure 3From: The inhibition of the mammalian DNA methyltransferase 3a (Dnmt3a) by dietary black tea and coffee polyphenolsMethyltransferase activity of the purified Dnmt3a-C. Example of the methylation kinetics carried out with purified Dnmt3a-C. Initial slopes were determined by linear regression analysis of the initial linear parts of the reaction progress curves.Back to article page
