Involved in the protection against hypochlorous acid (HOCl), the active ingredient of bleach, which kills bacteria by causing protein aggregation. Functions as an efficient holdase chaperone that protects the substrates of the major folding systems GroEL\/GroES and DnaK\/DnaJ\/GrpE from aggregation. In addition, it prevents the irreversible oxidation of its substrates through the formation of mixed disulfide complexes. After bleach stress, it transfers its substrates to the GroEL\/GroES and DnaK\/DnaJ\/GrpE foldases.
