"Bacillus subtilis is an aerobic, endospore forming, rod-shaped Gram-positive bacterium. It has a relatively small genome of 4,215,606 bp with 4,197 protein coding genes. It is considered a model organism to study natural phenomena, such as chromosome replication, sporulation or swarming motility. Furthermore, many bacterial pathogens are closely related to B. subtilis, making it a highly significant system for research on potential targets for drug therapeutics. Although B. subtilis is among the best characterised bacterial systems, many of its gene products are still non-annotated, completely uncharacterised and/or their post-translational landscape is unknown. In the current study we aim at broadening the available information on Bacillus subtilis by providing a comprehensive resource for the microbial community encompassing a wide array of information at the genome, proteome, phosphoproteome and acetylome level."
