The phage shock protein response

WebbThe phage-shock-protein (Psp) system of Yersinia enterocolitica encodes a stress response that is essential for viability when the secretin component of its Ysc type III secretion system is produced. Therefore, Y. enterocolitica psp null mutants are completely avirulent in a mouse model of infection.

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 ...
