pubpic2008thielgesWe report a preliminary analysis of (methyl-d3) methionine residues, Met16, Met20, and Met42, within DHFR. The results confirm the sensitivity of the carbon−deuterium bonds to their local protein environment and demonstrate that dihydrofolate reductase is electrostatically and dynamically heterogeneous.
