Application


  • Nε-Acetyl L-α Lysine Improves Activity and Stability of α-Amylase at Acidic Conditions: A Comparative Study with other Osmolytes. This study highlights the use of Nε-Acetyl-ʟ-lysine in enhancing the functional stability and activity of α-amylase under acidic conditions, demonstrating its potential as a valuable additive in industrial enzyme applications (Joghee et al., 2020).

Actions biochimiques/physiologiques

Nε-Acetyl-L-lysine (L-AcK) is an R-chain N-acetylated α amino acid used together with other lysine analogues to differentiate and characterized various aminoacylases and regulator 2 (Sir2) enzymes/sirtuins.

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

After heating N alpha-acetyllysine and glucose for 4 h at 90 degrees C in the dry state and subsequent acid hydrolysis with 7.8 N HCl, preparative fractionation of the dihydrochlorides of furosine and pyridosine was achieved by cation-exchange chromatography. The

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.

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

Histone deacetylase (HDAC) enzymes modulate gene expression through the deacetylation of acetylated lysine residues on histone proteins. They operate in biological systems as part of multiprotein corepressor complexes. To understand the reactivity of isolated HDACs and the contribution of cofactor
