Protein
Thiol:disulfide interchange protein CycY
Organism
Bradyrhizobium diazoefficiens (strain JCM 10833 / IAM 13628 / NBRC 14792 / USDA 110)
Function
Required for disulfide bond formation in some periplasmic proteins. Also acts as a disulfide oxidoreductase in cytochromes c biogenesis. The cysteines of apocytochromes c must be in the reduced state for covalent linkage between the two moieties to occur (By similarity).
Similarity
Belongs to the thioredoxin family. DsbE subfamily.
