== Function ==
[https://www.uniprot.org/uniprot/CYCY_BRADU CYCY_BRADU] 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).

== Publication Abstract from PubMed ==
CcmG is unlike other periplasmic thioredoxin (TRX)-like proteins in that it has a specific reducing activity in an oxidizing environment and a high fidelity of interaction. These two unusual properties are required for its role in c-type cytochrome maturation. The crystal structure of CcmG reveals a modified TRX fold with an unusually acidic active site and a groove formed from two inserts in the fold. Deletion of one of the groove-forming inserts disrupts c-type cytochrome formation. Two unique structural features of CcmG-an acidic active site and an adjacent groove-appear to be necessary to convert an indiscriminately binding scaffold, the TRX fold, into a highly specific redox protein.
