Comments
[?]
| FUNCTION | Required to facilitate the formation of correct disulfide bonds in some periplasmic proteins and for the assembly of the periplasmic c-type cytochromes. Acts by transferring electrons from cytoplasmic thioredoxin to the periplasm. This transfer involves a cascade of disulfide bond formation and reduction steps. |
| CATALYTIC ACTIVITY | Reaction=[protein]-dithiol + NAD(+) = [protein]-disulfide + NADH + H(+); Xref=Rhea:RHEA:18749, Rhea:RHEA-COMP:10593, Rhea:RHEA- COMP:10594, ChEBI:CHEBI:15378, ChEBI:CHEBI:29950, ChEBI:CHEBI:50058, ChEBI:CHEBI:57540, ChEBI:CHEBI:57945; EC=1.8.1.8; |
| CATALYTIC ACTIVITY | Reaction=[protein]-dithiol + NADP(+) = [protein]-disulfide + NADPH + H(+); Xref=Rhea:RHEA:18753, Rhea:RHEA-COMP:10593, Rhea:RHEA- COMP:10594, ChEBI:CHEBI:15378, ChEBI:CHEBI:29950, ChEBI:CHEBI:50058, ChEBI:CHEBI:57783, ChEBI:CHEBI:58349; EC=1.8.1.8; |
| SUBCELLULAR LOCATION | Cell inner membrane; Multi-pass membrane protein. |
| SIMILARITY | Belongs to the thioredoxin family. DsbD subfamily. |
