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 Phage shock protein (Psp) response maintains bacterial membrane integrity during extracytoplasmic stress. The central component of this system is a 2 5 kDa protein, which was observed during filamentous phage infection in Escherichia coli but was absent in non-infected cells [1].
Webb15 feb. 2024 · The phage shock protein (Psp) stress-response system protects bacteria from envelope stress through a cascade of interactions with other proteins and membrane lipids to stabilize the cell membrane. WebbAll extant organisms must have evolved suitable sensors, signaling systems, and response mechanisms allowing them to survive under the conditions they are likely to encounter. …

WebbThe phage shock protein (Psp) F regulon response in Escherichia coli is thought to be induced by impaired inner membrane integrity and an associated decrease in proton motive force (pmf). Mechanisms by which the Psp system detects the stress signal and responds have so far remained undetermined. Here we demonstrate that PspA and PspG directly …
