abstract：:The gene products from an 8-kb region adjacent to the 3' end of the ptx operon are required by Bordetella pertussis for the export of pertussis holotoxin. At least one of these gene products (PtlC) is specifically required for the export of assembled holotoxin from the periplasmic space. ptlC mutants exhibit a 20-fold...
