CC   -!- FUNCTION: The phage shock protein (psp) operon (pspABCDE) may play a
CC       significant role in the competition for survival under nutrient- or
CC       energy-limited conditions. PspB is involved in transcription regulation
CC       (By similarity). {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Cell inner membrane {ECO:0000250}; Single-pass
CC       membrane protein {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the PspB family. {ECO:0000305}.
