Protein
Acid stress chaperone HdeB
Organism
Escherichia coli O6:H1 (strain CFT073 / ATCC 700928 / UPEC)
Function
Required for optimal acid stress protection, which is important for survival of enteric bacteria in the acidic environment of the host stomach. Exhibits a chaperone-like activity at acidic pH by preventing the aggregation of many different periplasmic proteins.
Similarity
Belongs to the HdeB family.
