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
CC regulation. {ECO:0000269|PubMed:1712397}.
CC -!- SUBUNIT: Interacts with PspA; could bind PspA only in the presence of
CC PspC. {ECO:0000269|PubMed:12562786}.
CC -!- INTERACTION:
CC P0AFM9; P0AFN2: pspC; NbExp=5; IntAct=EBI-6408513, EBI-1134561;
CC -!- SUBCELLULAR LOCATION: Cell inner membrane; Single-pass membrane
CC protein.
CC -!- INDUCTION: By heat, ethanol, osmotic shock and infection by filamentous
CC bacteriophages. {ECO:0000269|PubMed:1712397}.
CC -!- SIMILARITY: Belongs to the PspB family. {ECO:0000305}.
