    Abstract Numerous interacting protein partners exist without recognized interactive domains, necessitating a standardized methodology to decipher more in-depth interaction profiles. Here, we present a protocol to reveal the binding partner of a secreted housekeeping enzyme, alcohol acetaldehyde dehydrogenase (Listeria adhesion protein), in Listeria monocytogenes through in silico modeling and in vivo experiments. We describe steps for target protein modeling, biophysical profiling, ClusPro docking optimization, protein variant modeling, and docking comparison. We then provide detailed procedures for in vitro and in vivo protein binding validation. For complete details on the use and execution of this protocol, please refer to Liu et al.

    Abstract Listeria adhesion protein (LAP) is a secreted acetaldehyde alcohol dehydrogenase (AdhE) that anchors to an unknown molecule on the Listeria monocytogenes (Lm) surface, which is critical for its intestinal epithelium crossing. In the present work, immunoprecipitation and mass spectrometry identify internalin B (InlB) as the primary ligand of LAP (K
