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 … Webb1 aug. 2005 · The phage‐shock‐protein response Darwin, Andrew J. 2005-08-01 00:00:00 Introduction The Gram‐negative bacterial cell envelope controls the passage of molecules into and out of the cell, includes structures like the cell wall, flagella and complex secretion systems, and provides an ion‐permeability barrier for the establishment of the …

Webb1 sep. 2005 · The phage-shock-protein (Psp) system responds to extracytoplasmic stress that may reduce the energy status of the cell. It is conserved in many different bacteria and has been linked to... 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 ]. flumed rangehood

WebbThe temperature-sensitive bacteriophage λ c 1857 repressor protein rapidly renatures after thermal inactivation. E. coli mutants in the heat shock protein genes dnaK, dnaJ , and grpE do not efficiently reactivate heat-denatured repressor. Our results suggest that protein refolding is promoted by heat shock proteins and that such a process is the basis of the … Webb25 sep. 2024 · The phage shock protein (Psp) stress-response system protects bacteria from envelope stress and stabilizes the cell membrane.
