Identification of Substrates of Secreted Bacterial Protease by APEX2-Based Proximity Labeling.The interactions between bacterial virulence factors and host receptors play a critical role during bacterial infection.  Herein, we report an APEX2-based live cell proximity labeling strategy in combination with high-resolution quantitative mass spectrometry to profile the substrates of Helicobacter pylori HtrA protease on the membrane of human stomach epithelial cells.
