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 ... WebbThe Psp response was discovered by Peter Model and his colleagues at the Rockefeller University in New York City. They noticed that infection of Escherichia coli cells by the filamentous phage f1 and production of the phage-encoded secretin (a pore-forming protein) caused massive production of a bacterial protein they called PspA [ 8 ]. cosita\u0027s antwerpen
