4D-Acetylation Proteomics Services

Protein acetylation modifications are regulated by acetyltransferases and deacetylases and vary with metabolic environments. Their modifications often occur on metabolic enzymes, which regulate metabolic pathways and metabolic enzyme activities and participate in downstream metabolite changes. Protein acetylation is the most common type of acylation modification and refers to covalent binding acetyl groups (e.g., acetyl coenzyme A and other donors) to lysine residues of substrate proteins catalyzed by acetyltransferases. The above process mainly occurs at the theε-NH2 position of the protein lysine residue, and its molecular weight will increase by 42.01Da. Furthermore, mass spectrometry can accurately determine whether the molecular weight has a corresponding mass shift and analyze the acylated modified peptides and sites.
