Post-translational modification of proteins is a reversible mechanism of cellular adaptation to changing environmental conditions. In eukaryotes, the physiological relevance of N-ɛ-lysine protein acetylation is well demonstrated. In recent times, important roles in the regulation of metabolic processes in bacteria are being uncovered, adding complexity to cellular regulatory networks.

The aim of this mini-review is to sum up the current state-of-the-art in the regulation of bacterial physiology by protein acetylation. Current knowledge on the molecular biology aspects of known bacterial protein acetyltransferases and deacetylases will be summarized. Protein acetylation in Escherichia coli, Salmonella enterica, Bacillus subtilis, Rhodopseudomonas palustris and Mycobacterium tuberculosis, will be explained in the light of their physiological relevance. Progress in the elucidation of bacterial acetylomes and the emerging …
