What is it about?

General stress response (GSR) systems protect bacteria from a diverse range of physical and chemical stressors. We have developed Erythrobacter litoralis as a new genetic model to study GSR in Alphaproteobacteria and show that three HWE-family histidine kinases collectively regulate GSR transcription via σEcfG. Visible light is a GSR regulatory signal in E. litoralis, and LovK is a blue-light photosensor kinase that functions as a dark activated GSR regulator.
