Reaction: Sulfite is oxidized to sulfate
- in pathway: Sulfide oxidation to sulfate
Sulfite oxidase oxidizes sulfite to sulfate which is among the most important macronutrients in cells and the fourth most abundant anion in human plasma (300 micromolar). The enzyme has a molybdenum-molybdopterin cofactor (MoCo) bound (Wilson et al. 2006, Feng et al. 2007).
