Swiss:P97207 is a subunit of the terminal quinol oxidase present in the plasma membrane of Acidianus ambivalens, with calculated molecular mass of 20.4 kDa [1]. 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 are fused together in a single polypeptide in Swiss:Q8AAF0. [1]. 9023221. The terminal quinol oxidase of the hyperthermophilic archaeon Acidianus ambivalens exhibits a novel subunit structure and gene organization. Purschke WG, Schmidt CL, Petersen A, Schafer G;.
