Sirtuin-Dependent Reversible Lysine Acetylation Controls the Activity of Acetyl Coenzyme A Synthetase in Campylobacter jejuni

Abstract

This work provides the experimental evidence needed to support the assignment of function to three key enzymes, two of which control the reversible posttranslational modification of an active-site lysyl residue of the central metabolic enzyme acetyl-CoA synthetase ( Cj Acs). We can now generate Campylobacter jejuni mutant strains defective in these functions, so we can establish the conditions in which this mode of regulation of Cj Acs is triggered in this bacterium.
