CC   -!- FUNCTION: Redox regulated molecular chaperone. Protects both thermally
CC       unfolding and oxidatively damaged proteins from irreversible
CC       aggregation. Plays an important role in the bacterial defense system
CC       toward oxidative stress. {ECO:0000255|HAMAP-Rule:MF_00117}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_00117}.
CC   -!- PTM: Under oxidizing conditions two disulfide bonds are formed
CC       involving the reactive cysteines. Under reducing conditions zinc is
CC       bound to the reactive cysteines and the protein is inactive.
CC       {ECO:0000255|HAMAP-Rule:MF_00117}.
CC   -!- SIMILARITY: Belongs to the HSP33 family. {ECO:0000255|HAMAP-
CC       Rule:MF_00117}.
