Webb(Figure 1). Filamentous phage infection induces pspA operon expression because a phage-encoded outer membrane pore-forming ‘‘secretin’’ protein (pIV) has a tendency to mislocalize within the E. coli envelope [3]. The Psp response is also induced by environmental shocks that can negatively affect the cell envelope. This, together with ...
