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. This article summarizes what is known about … 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].
Webb30 juni 2005 · The phage-shock-protein response Introduction. The Gram-negative bacterial cell envelope controls the passage of molecules into and out of the cell,... 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 …
