Protein Acetylation in Pathogen Virulence and Host Defense: In Vitro Detection of Protein Acetylation by Radiolabeled Acetyl Coenzyme A.Methods Mol Biol 2019; 1991:23-32MM
Protein acetylation has emerged as a common modification that modulates multiple aspects of protein function, including localization, stability, and protein-protein interactions. It is increasingly evident that protein acetylation significantly impacts the outcome of host-microbe interactions. In order to characterize novel putative acetyltransferase enzymes and their substrates, we describe a simple protocol for the detection of acetyltransferase activity in vitro. Purified proteins are incubated with 14C-acetyl CoA and separated electrophoretically, and acetylated proteins are detected by phosphorimaging or autoradiography.
