The PtlE protein of Bordetella pertussis has peptidoglycanase activity required for Ptl-mediated pertussis toxin secretion.

Journal of bacteriology - 1 Jun 2002

Rambow-Larsen Amy A, Weiss Alison A

Abstract excerpt

Pertussis toxin of Bordetella pertussis is secreted by a type IV secretion system comprised of the products of the nine ptl (pertussis toxin liberation) genes. These proteins are believed to form a complex spanning both the inner and outer membranes and passing through the peptidoglycan layer. Peptidoglycan acts as a barrier for transport through the periplasm of large folded molecules. Assembled pertussis toxin...
