Eukaryotic organelles have developed elaborate protein quality control systems to ensure their normal activity, among which Deg/HtrA proteases play an essential role. Plant Deg2 protease is a homologue of prokaryotic DegQ/DegP proteases and is located in the chloroplast stroma, where its proteolytic activity is required to maintain the efficiency of photosynthetic machinery during stress. Here, we demonstrate that Deg2 exhibits dual protease-chaperone activities, and we present the hexameric str ...[more]
