Molecular investigation into the roles of Sigma B and the Stressosome in the response of Listeria monocytogenes to environmental stress

Abstract:
The alternative sigma factor, SigB, has been studied extensively in Listeria monocytogenes, Bacillus subtilis and Staphylococcus aureus, and is known to regulate the general stress response in these bacteria. The activation of SigB by a stress occurs via a signalling cascade, upstream of which is the stressosome complex. The stressosome is a large protein complex composed of RsbS, RsbT and RsbR proteins, with the RsbR proteins hypothesised to function as stress sensors. RsbR has four paralogues, Lmo0161, Lm0799, Lmo1642 and Lmo1842, of which only Lmo0799 has been established to act as a stress sensor. Lmo0799 is a blue light sensor, but somewhat surprisingly inactivation of the corresponding gene does not result in sensitivity to blue light. In the current study, environmental factors including growth phase and temperature, along with exposure to ethanol or alternative carbon sources, were identified to alter the sensitivity of L. monocytogenes to killing by blue light.
