The Burden Borne by Protein Methyltransferases: Rates and Equilibria of Nonenzymatic Methylation of Amino Acid Side-Chains by SAM in Water

Authors : Lewis Jr, Charles A. (2021)

SAM is a powerful methylating agent, with a methyl group transfer potential matching the phosphoryl group transfer potential of ATP. SAM-dependent N-methyltransferases have evolved to catalyze the modification of specific lysine residues in histones and transcription factors, in addition to generating epinephrine, N-methylnicotinamide, and a quaternary amine (betaine) that is used to maintain osmotic pressure in plants and halophilic bacteria. To assess&...
