Custom Acetylation & Deacetylation Peptide Array Service


Protein acetylation is one of the major post-translational modifications (PTMs) in eukaryotes, in which the acetyl group from acetyl coenzyme A (Ac-CoA) is transferred to a specific site on a polypeptide chain. Two types of acetylation are known to occur widely in proteins: α-amino group of the N-terminus and ε-amino group of lysine residues. Figure 1 shows the schematic overview of acetylation and deacetylation in proteins, such as histone and lysine residue.



Fig.1 The schematic overview of acetylation and deacetylation: A. Acetylation of α-amino group of the N-terminus, catalyzed by N-terminal acetyltransferases (NATs), irreversible. B. Acetylation or deacetylation of ε-amino group of a lysine residue, catalyzed by lysine

acetyltransferases (KATs) or Lysine deacetylases (KDACs), reversible.


Acetylation and deacetylation of proteins play a crucial function in the processes of cellular metabolism. To efficiently complete a high throughput screening for the substrates of acetylase or deacetylase of interest, ALL Chemistry carefully chooses the peptide substrates labeled/non-labeled by acetyl group in special sites (N-terminal and Lysine) from our database of acetylation sites and custom acetylation or deacetylation peptide array for our clients. Figure 2 shows a model of the peptide substrates array for acetylase or deacetylase: A. lysine acetylation and acetylation peptide array service; B. α-amino group of the N-terminus.
