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).

Biochem/physiol Actions

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.

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

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

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
