CC   -!- FUNCTION: Required for optimal acid stress protection. Exhibits a
CC       chaperone-like activity only at low pH by suppressing non-specifically
CC       the aggregation of denaturated periplasmic proteins.
CC       {ECO:0000255|HAMAP-Rule:MF_00946}.
CC   -!- SUBCELLULAR LOCATION: Periplasm {ECO:0000255|HAMAP-Rule:MF_00946}.
CC   -!- SIMILARITY: Belongs to the HdeA family. {ECO:0000255|HAMAP-
CC       Rule:MF_00946}.
