CC   -!- SUBCELLULAR LOCATION: Cell inner membrane; Multi-pass membrane protein.
CC   -!- INDUCTION: By growth arrest in general, by carbon, phosphate, and
CC       nitrogen starvation as well as osmotic shock and oxidative stress.
CC   -!- DISRUPTION PHENOTYPE: Cells are sensitive to exposure to ethanol but
CC       not heat in stationary phase. {ECO:0000269|PubMed:9829921}.
CC   -!- MISCELLANEOUS: Overexpression of uspB causes cell death in stationary
CC       phase.
CC   -!- SIMILARITY: Belongs to the universal stress protein B family.
CC       {ECO:0000305}.
