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.

Webb16 juni 2024 · The phage shock protein (Psp) response maintains integrity of the inner membrane (IM) in response to extracytoplasmic stress conditions and is widely distributed amongst enterobacteria. Its central component PspA, a member of the IM30 peripheral membrane protein family, acts as a major effector of the system through its direct … 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 …
