Sirtuins are NAD (+)-dependent enzymes that deacetylate a variety of cellular proteins and in some cases catalyze protein ADP-ribosyl transfer. The catalytic mechanism of deacetylation is proposed to involve an ADPR-peptidylimidate, whereas the mechanism of ADP-ribosyl transfer to proteins is

The folate-coupled metabolic enzyme MTHFD2 (the mitochondrial methylenetetrahydrofolate dehydrogenase/cyclohydrolase) confers redox homeostasis and drives cancer cell proliferation and migration. Here, we show that MTHFD2 is hyperacetylated and lysine 88 is the critical acetylated site. SIRT3, the major deacetylase in mitochondria

N(epsilon)-acetylation of lysine (1) is a reversible post-translational modification with a regulatory role that rivals that of phosphorylation in eukaryotes. No general methods exist to synthesize proteins containing N(epsilon)-acetyllysine (2) at defined sites. Here we demonstrate the site-specific incorporation of

Antibodies directed against chemical specific protein modifications are valuable tools to detect and comparatively quantify protein modifications. Both Nepsilon-(dichloroacetyl)-L-lysine and Nepsilon-(trichloroacety)l-L-lysine have been detected as modified amino acids in liver and kidneys of rats treated with perchloroethene (PER) after proteolysis.

Sirtuins are protein-modifying enzymes distributed throughout all forms of life. These enzymes bind NAD(+), a universal metabolite, and react it with acetyllysine residues to effect deacetylation of protein side chains. This NAD(+)-dependent deacetylation reaction has been observed for sirtuin enzymes

We have previously shown that incubation of the model protein glucose-6-phosphate dehydrogenase (Glu-6-PDH) from the bacterium Leuconostoc mesenteroides with 4-hydroxy-2-nonenal (HNE), a major product of lipid peroxidation, results in the formation of cross-linked protein. HNE-modified protein is resistant to proteolytic

Recent studies have implicated acetylation of several nuclear proteins such as histones and p53 on their epsilon-portion of lysine residues in eukaryotic transcription. Here we raised a specific polyclonal antibody against epsilon-acetylated lysine. Using the antibody, we detected hypernuclear acetylation

Acetylation of specific lysine residues in the N-terminal domains of core histones is a biochemical marker of active genes. To determine the spatial and temporal distribution of this reversible posttranslational modification, affinity-purified polyclonal antibodies recognizing the epitope epsilon-acetyllysine have been

By overexpressing the C-terminal domain of the ribosomal protein L11 to decrease release factor 1-mediated termination of protein translation, enhanced amber suppression is achieved in E. coli. This enhanced amber suppression efficiency allows the genetic incorporation of three N(epsilon)-acetyl-l-lysines into

Tandem mass spectrometry (MS/MS) is a powerful tool for characterization of post-translationally modified proteins, including epsilon-N-acetyllysine-containing species. Previous reports indicate that epsilon-N-acetyllysine immonium ions are useful marker ions for peptides containing epsilon-N-acetyllysine, but the specificity and sensitivity of these ions
