Abstract: The present disclosure relates to methods for exporting target proteins (e.g., surface lipoproteins) from the cytosol to the extracellular surface of bacterial cells using surface lipoprotein assembly modulator (SLAM) polypeptides. The use of SLAM polypeptides in a method of preparing vaccines useful in the prevention of bacterial infectious diseases is also taught.

Abstract: The disclosure provides immunogenic compositions comprising a polypeptide comprising a C-lobe domain or an N-lobe domain of a HIBP surface receptor protein obtainable from or obtained from a Gram-negative bacterial species. The HIBP surface receptor proteins have been modified in such a manner that they are unable to bind host iron binding protein. Methods of making and using these immunogenic positions to prepare animal and human vaccines are also provided.
