Functional information

Function Uniprot Acts as a transcriptional repressor, inhibiting expression in vitro. Probably redox-responsive. The apo- but not holo-form binds to its own promoter as well as that of groEL2. Oxidized apo-form and nitrosylated holo-form also bind DNA. The apo-form has been shown to act as a protein disulfide reductase, but also not to act as a protein disulfide reductase.
Role Repressor
Protein family Whib
Structure (PDB ID) 5OAY
