The phage shock protein response
WebbThe Phage shock protein (Psp) response is an extracytoplasmic stress response. The central component of this system is PspA, a protein that mediates the physiological response to membrane stress. PspA is also involved in regulating its own transcription and that of the psp operon, forming a positive feedback loop. PspA has been previously … WebbA partial amino acid sequence showed that this protein was the phage-shock protein PspA. PspA is known to be induced in E. coli cells under extreme stress conditions. The results …
