Namephage shock protein regulon
DescriptionThis property describes a regulon present in E. coli and a number of other species induced by various stresses including osmotic shock, ethanol, heat, and expression of various secretins, as occurs with infection by certain filamentous phage. A common thread to these stressors may be compromise of the inner membrane and decrease of the protonmotive force. Most proteins of the regulon occur in a single operon, but at least one member, pspG, is located elsewhere in most genomes. The signature genes of the the phage shock regulon are the sigma-54-dependent positive regulator PspF, PspA which binds to and inhibits PspF, and PspB and PspC which act together as both regulatory and effector proteins of the phage shock regulon. PspG occurs in most but not all phage shock-positive genomes, while PspD and PspE are found only in a minority of phage shock operons.
