Acetylome analysis of Bacillus amyloliquefaciens

Lysine acetylation is a major post-translational modification that plays an important regulatory role in almost every aspects in both eukaryotes and prokaryotes. Bacillus amyloliquefaciens, a Gram-positive bacterium, is very effective for the control of plant pathogens. Here, we conducted the first lysine acetylome in B. amyloliquefaciens through a combination of highly sensitive immune-affinity purification and high-resolution LC−MS/MS. Overall, we identified 3268 lysine acetylation sites in 1254 proteins. Acetylated proteins are associated with a variety of biological processes and a large fraction of these proteins are involved in metabolism. These data serves as an important resource for further elucidation of the physiological role of lysine acetylation in B. amyloliquefaciens.
