Structurally diverse natural products that cause potassium leakage trigger multicellularity in Bacillus subtilis.
We report a previously undescribed quorum-sensing mechanism for triggering multicellularity in Bacillus subtilis. B. subtilis forms communities of cells known as biofilms in response to an unknown signal. We discovered that biofilm formation is stimulated by a variety of small molecules produced by bacteria--including the B. subtilis nonribosomal peptide surfactin--that share the ability to ind...
متن کاملDifferent roles for KinA, KinB, and KinC in the initiation of sporulation in Bacillus subtilis.
Activation (phosphorylation) of the transcription factor encoded by spo0A is essential for the initiation of sporulation in Bacillus subtilis. At least three histidine protein kinases are involved in the phosphorylation of Spo0A. Under some growth conditions, KinA was the primary kinase, but under other conditions, KinB had the more critical role. KinC was required for the initial activation of...
متن کاملAdaptation of Bacillus subtilis to Life at Extreme Potassium Limitation
Potassium is the most abundant metal ion in every living cell. This ion is essential due to its requirement for the activity of the ribosome and many enzymes but also because of its role in buffering the negative charge of nucleic acids. As the external concentrations of potassium are usually low, efficient uptake and intracellular enrichment of the ion is necessary. The Gram-positive bacterium...
متن کاملAnalysis of a suppressor mutation ssb (kinC) of sur0B20 (spo0A) mutation in Bacillus subtilis reveals that kinC encodes a histidine protein kinase.
sur0B20 is a mutation that suppresses the effects of spo0B delta B or spo0F221 mutations in Bacillus subtilis, sur0B20 is an allele of the spo0A gene (Glu-14 to Val-14 conversion) and restores the sporulation of spo0B or spo0F mutants to the wild-type level. Here, we report the isolation of suppressor mutations of sur0B20 (ssb). One of these mutations, ssb-12, severely impairs the suppressor ac...
