The enzymes involved in lysine methylation were first found to target histone and thus have been initially named histone methyltransferases and histone demethylases, following the naming mannequin for histone acetyltransferase and histone deacetylase. KMTs catalyze mono-, di-, or tri-methylation by transfering one, two, or three methyl groups, respectively, from S-adenosyl-L-methionine to the ε-amino group of a lysine residue.
The worth of creating in depth, tissue-specific maps of protein lysine acetylation sites is further underscored by the numerous function of posttranslational modifications in the evolution and phenotypic composition of vertebrates, as indicated by the numerous selective pressure gene regulatory parts close to posttranslational-modifying enzymes have come below in placental animals ( Lowe et al., 2011 ). Right here, we mixed an environment friendly method for protein extraction from tissue samples with lysine-acetylated peptide immunoprecipitation and excessive-accuracy tandem mass spectrometric (MS/MS) measurements, which allowed us to generate an atlas of lysine acetylation websites in 16 totally different rat tissues.

With the intention to replicate, the herpes virus requires arginine , one other amino acid that is frequent in meals and necessary to human life
