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}.
