The addition of the acetyl group neutralizes this positive charge and hence reduces the binding between histones and …

Web3 H-acetyl CoA and 14 C-acetyl CoA are commonly used radiolabeled substrates for studying in vitro acetylation of histones and other proteins. Acetylation typically occurs at either the N-terminus of a protein or peptide, or on lysine residues within a protein. Alternatively, acetylation can be studied in cells using 3 H-sodium acetate. Radioactive substrates for … WebA series of proteomic studies have demonstrated that AARSs have levels of lysine acetylation much higher than those of other proteins in Escherichia coli. To study AARS acetylation, 25 site-specifically acetylated variants of four AARSs were generated by the genetic code expansion strategy.
