Description | The sulfate ion consists of one sulfur (S) and four bound oxygen (O). In thiosulfate, one O is replace by S. This property describes the oxidation of thiosulfate to sulfate. In most species, sulfur oxidation begins further upstream, with sulfide or elemental sulfur. Molecular markers of those processes are not included here. Key proteins in thiosulfate oxidation to sulfate include SoxA, SoxB, SoxX, SoxY, and SoxZ. SoxYZ is a heterodimer. SoxXA is a heterodimeric c-type cytochrome. SoxB is monomeric. |
