6.1.1.1 | acetylation |
tyrosyl-tRNA synthetase (TyrRS) in Escherichia coli is acetylated at multiple lysine residues. Acetylation at K85, K235, and K238 impairs the enzyme activity, by genetic-code-expansion strategy to site-specifically incorporate Nepsilonacetyl-l-lysine into selected positions of TyrRS for in vitro characterization. Lysine residue K355 is never acetylated. Most acetylated lysine residues in TyrRS are sensitive to the Escherichia coli deacetylase CobB but not YcgC, overview.
