| 背景 | Lysine is subject to a wide array of regulatory post-translational modifications due to its positively charged ε-amino group side chain. The most prevalent of these are ubiquitination and acetylation, which are highly conserved among prokaryotes and eukaryotes (1,2). Acyl group transfer from the metabolic intermediates acetyl-, succinyl-, malonyl-, glutaryl-, butyryl-, propionyl-, and crotonyl-CoA all neutralize lysine’s positive charge and confer structural alterations affecting substrate protein function. Lysine acetylation is catalyzed by histone acetyltransferases, HATs, using acetyl-CoA as a cofactor (3,4). Deacylation is mediated by histone deacetylases, HDACs 1-11, and NAD-dependent Sirtuins 1-7. Some sirtuins have little to no deacetylase activity, suggesting that they are better suited for other acyl lysine substrates (5). |

The chart shows the relative category distribution of proteins with malonylated lysine residues identified from peptides generated from a PTMScan® LC-MS/MS experiment of mouse liver tissue using PTMScan® Malonyl-Lysine [Mal-K] Immunoaffinity Beads. | |
The Motif Logo was generated from a PTMScan® LC-MS/MS experiment using 779 nonredundant tryptic mouse liver peptides immunoprecipitated with PTMScan® Malonyl-Lysine [Mal-K] Immunoaffinity Beads. The logo represents the relative frequency of amino acids in each position surrounding the central malonylated lysine residue. |
