Self-reinforcing activation of a cell-specific transcription factor by proteolysis of an anti-sigma factor in B. subtilis.
The transcription factor sigma(F), which is activated in a cell-specific manner during sporulation in B. subtilis, is initially held in an inactive complex by the anti-sigma factor SpoIIAB. The anti-anti-sigma factor SpoIIAA reacts with SpoIIAB.sigma(F) to induce the release of free sigma(F) and free SpoIIAB. We now report that free SpoIIAB is subject to proteolysis and that it is protected fro...

متن کاملCompetence in Bacillus subtilis is controlled by regulated proteolysis of a transcription factor.
Competence is a physiological state, distinct from sporulation and vegetative growth, that enables cells to bind and internalize transforming DNA. The transcriptional regulator ComK drives the development of competence in Bacillus subtilis. ComK is directly required for its own transcription as well as for the transcription of the genes that encode DNA transport proteins. When ComK is sequester...
متن کاملExtracellular signal protein triggering the proteolytic activation of a developmental transcription factor in B. subtilis
We present biochemical evidence for an intercellular signal transduction pathway in B. subtilis. This pathway governs the conversion of the proprotein pro-sigma E to mature transcription factor sigma E. Proteolytic processing is mediated by the membrane protein SpollGA and is triggered by the inferred extracellular signal protein SpollR. A factor in conditioned medium from B. subtilis cells eng...
