摘要

Bacterial twin-arginine translocases can export fully folded proteins from the cytoplasm. Such proteins are usually resistant to proteolysis. Here we show that multiple extracellular proteases degrade the B. subtilis Tat substrate YwbN. This suggests either that secreted YwbN is not fully folded or that folded YwbN exposes protease cleavage sites.
