The phage shock protein response
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].
