thioredoxin family protein
Thioredoxins are small enzymes that participate in redox reactions, via the reversible oxidation of an active centre disulfide bond. (from Pfam)
protein-disulfide reductase DsbD domain-containing protein
This entry represents the N-terminal domain of DsbD, a transmembrane electron transporter [1-3]. DsbD binds to a DsbC dimer and selectively activates it using electrons from the cytoplasm. The N-terminal domain of DsbD (DsbDN) is capable of forming disulfides with oxidized DsbC, DsbE, or DsbG as well as with reduced DsbD [1-3]. [1]. 12033924.

cytochrome c biogenesis protein CcdA
This family consists of the transmembrane (i.e. non-catalytic) region of Cytochrome C biogenesis proteins also known as disulphide interchange proteins. These proteins posses a protein disulphide isomerase like domain that is not found within the aligned region of this family. [1]. 7623667.

protein-disulfide reductase DsbD family protein
protein-disulfide reductase DsbD family protein, similar to DsbD that facilitates the formation of correct disulfide bonds in some periplasmic proteins and is required for the assembly of the periplasmic c-type cytochromes
