A simplified scheme of the main pathways and enzymes involved in the oxidation of inorganic sulfur compounds by ASOM as explained in the text. The enzymes in the pathway lines are: Sqr, sulfide: quinone oxidoreductase; Sor, sulfur oxygenase reductase; Pdo, persulfide dioxygenase; Sat, ATP sulfurylase; Sox, sulfur oxidation complex; Tqo, thiosulfate:quinol oxidoreductase; TetH, tetrathionate hydrolase.
