A putative autotransporter. The N-terminus is on the cell surface as it is accessible to trypsin. The signal peptide, cleaved at the inner membrane, guides the autotransporter protein to the periplasmic space. Insertion of the C-terminal translocator domain in the outer membrane forms a hydrophilic pore for translocation of the passenger domain to the bacterial cell surface, with subsequent cleavage. Finally, the mature protein remains tightly associated with the bacterium (Probable).
