== 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.


==Function==
Structure of CcmG/DsbE at 1.14 A resolution: high-fidelity reducing activity in an indiscriminately oxidizing environment.,Edeling MA, Guddat LW, Fabianek RA, Thony-Meyer L, Martin JL Structure. 2002 Jul;10(7):973-9. PMID:12121652<ref>PMID:12121652</ref>
[[http://www.uniprot.org/uniprot/CYCY_BRAJA CYCY_BRAJA]] Required for disulfide bond formation in some periplasmic proteins. Also act 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).
