AC MF_00821; DC Protein; auto TR HAMAP; MF_00821; -; 1; level=0 XX Names: SecB XX ID SECB DE RecName: Full=Protein-export protein SecB; GN Name=secB; XX CC -!- FUNCTION: One of the proteins required for the normal export of CC preproteins out of the cell cytoplasm. It is a molecular chaperone that CC binds to a subset of precursor proteins, maintaining them in a CC translocation-competent state. It also specifically binds to its CC receptor SecA. CC -!- SUBUNIT: Homotetramer, a dimer of dimers. One homotetramer interacts CC with 1 SecA dimer. CC -!- SUBCELLULAR LOCATION: Cytoplasm. CC -!- SIMILARITY: Belongs to the SecB family.
