This family includes the B. subtilis YdjO protein Swiss:O34759, which is functionally uncharacterised. This is not a homologue of E. coli YdjO, Swiss:P76210. B. subtilis YdjO is cold-inducible [1]. Its expression is induced by the extracytoplasmic function sigma factor sigma-W [2]. This family of proteins is found in bacteria. Proteins in this family are approximately 60 amino acids in length.
