Protein acetylation plays critical roles in many biological processes both in eukaryotes and prokaryotes. In the past few years, tremendous of acetylated proteins and acetylation sites have been identified in bacteria. Here, we mainly focus on bacterial Nε-acetylation. First introduce the history of protein acetylation from it was first discovered, and discussed the latest progresses in bacterial protein acetylation. Then discussed the role of acetylation on several important proteins, such as ACS and CheY. We also addressed the advantages and possibility of using protein microarray for the identification of novel acetylated proteins, and the discovery of novel acetyltransferase and deacetyltransferase in bacteria. The crosstalks between protein acetylation and ubiquitination, acetylation and phosphorylation were also discussed. To discover more acetylated protein from bacteria in a high-throughput fashion, currently, the best strategy is the combination of immunoprecipitation enrichment, high-resolution mass spectrometry and bioinformatics analysis. We discussed the latest advancement of this strategy. Finally, the future trends for bacterial protein acetylation study was discussed.
