pfam04173: DoxD 
TQO small subunit DoxD
DoxD is a subunit of the terminal quinol oxidase present in the plasma membrane of Acidianus ambivalens, with calculated molecular mass of 20.4 kDa. Thiosulphate:quinone oxidoreductase (TQO) is one of the early steps in elemental sulphur oxidation. A novel TQO enzyme was purified from the thermo-acidophilic archaeon Acidianus ambivalens and shown to consist of a large subunit (DoxD) and a smaller subunit (DoxA). The DoxD- and DoxA-like two subunits can be fused together in a single polypeptide.
