This book reviews the chemical, regulatory, and physiological
mechanisms of protein arginine and lysine methyltransferases, as
well as nucleic acid methylations and methylating enzymes. Protein
and nucleic acid methylation play key and diverse roles in cellular
signalling and regulating macromolecular cell functions. Protein
arginine and lysine methyltransferases are the predominant enzymes
that catalyse S-adenosylmethionine (SAM)-dependent methylation of
protein substrates. These enzymes catalyse a nucleophilic
substitution of a methyl group to an arginine or lysine side chain
nitrogen (N) atom. Cells also have additional protein
methyltransferases, which target other amino acids in peptidyl side
chains or N-termini and C-termini, such as glutamate, glutamine,
and histidine. All these protein methyltransferases use a similar
mechanism. In contrast, nucleic acids (DNA and RNA) are substrates
for methylating enzymes, which employ various chemical mechanisms
to methylate nucleosides at nitrogen (N), oxygen (O), and carbon
(C) atoms. This book illustrates how, thanks to there ability to
expand their repertoire of functions to the modified substrates,
protein and nucleic acid methylation processes play a key role in
cells.
