The Motif Logo was generated from a PTMScan® LC-MS/MS experiment using 190 nonredundant tryptic peptides derived from mouse liver tissue immunoprecipitated with PTMScan® Glutaryl-Lysine [Glut-K] Immunaffinity Beads. The logo represents the relative frequency of amino acids in each position surrounding the central glutarylated residue within this data set.

Product Usage Information

Cells are lysed in a urea-containing buffer, cellular proteins are digested by proteases, and the resulting peptides are purified by reversed-phase solid-phase extraction. Peptides are then subjected to immunoaffinity purification using a PTMScan® Motif Antibody conjugated to protein A agarose beads. Unbound peptides are removed through washing, and the captured PTM-containing peptides are eluted with dilute acid. Reversed-phase purification is performed on microtips to desalt and separate peptides from antibody prior to concentrating the enriched peptides for LC-MS/MS analysis. CST recommends the use of PTMScan® IAP Buffer #9993 included in the kit. An alternate PTMScan® IAP Buffer Plus Detergent #9992, which may reduce nonspecific interactions, is available separately. A detailed protocol and Limited Use License allowing the use of the patented PTMScan® method are included with the kit.

Storage

Antibody beads supplied in IAP buffer containing 50% glycerol. Store at -20°C. Do not aliquot the antibody.

Product Description

PTMScan® Technology employs a proprietary methodology from Cell Signaling Technology (CST) for peptide enrichment by immunoprecipitation using a specific bead-conjugated antibody in conjunction with liquid chromatography (LC) tandem mass spectrometry (MS/MS) for quantitative profiling of post-translational modification (PTM) sites in cellular proteins. These include phosphorylation (PhosphoScan®), ubiquitination (UbiScan®), acetylation (AcetylScan®), and methylation (MethylScan®), among others. PTMScan® Technology enables researchers to isolate, identify, and quantitate large numbers of post-translationally modified cellular peptides with a high degree of specificity and sensitivity, providing a global overview of PTMs in cell and tissue samples without preconceived biases about where these modified sites occur.

Background

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).

Lysine glutarylation events predominate in the mitochondria and mainly occur on metabolic proteins. Similar to malonylation and succinylation, lysine glutaryl transfer is likely mediated by a combination of non-enzymatic, thermodynamic, and stoichiometric mechanisms driving the reaction in the acidic environment of the mitochondria in the presence of promiscuous acetyltransferases (6). SirT5 and glutaryl-CoA dehydrogenase (GCDH) knockout mice exhibit elevated levels of glutarylated proteins as do mice on a diet high in tryptophan. SirT5 is likely the main de-glutarylase, as demonstrated by its activity on carbamoyl phosphate synthase 1 (CPS1), a heavily glutarylated protein of the urea cycle (7).
