Function
Chaperedoxin that combines a chaperone activity with a redox-protective function (PubMed:16563353, PubMed:18657513, PubMed:29754824). Involved in the protection against hypochlorous acid (HOCl), the active ingredient of bleach, which kills bacteria by causing protein aggregation (PubMed:29754824). 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 (PubMed:29754824). After bleach stress, it transfers its substrates to the GroEL/GroES and DnaK/DnaJ/GrpE foldases (PubMed:29754824). Lacks oxidoreductase activity (PubMed:21498507, PubMed:29754824).
