Sulfite oxidase is a mitochondrial enzyme encoded by the SUOX gene and essential for the detoxification of sulfite which results mainly from the catabolism of sulfur-containing amino acids.

Sulfite oxidase [SO; EC 1.8.3.1] catalyses the physiologically vital oxidation of sulfite to sulfate, the terminal reaction in degradation of sulfur containing amino acids, cysteine and methionine.

In ATM3 insertion mutants of Arabidopsis thaliana, the activities of nitrate reductase and sulfite oxidase were decreased to approximately 50%, whereas the activities of xanthine dehydrogenase and aldehyde oxidase, whose activities also depend on iron-sulfur clusters, were virtually undetectable.

The structures of the C185S and C185A variants revealed that neither the Ser or Ala side chains appeared to closely interact with the Mo atom and that a third oxo group replaced the usual cysteine sulfur ligand at the Mo center, confirming earlier EXAFS work on the human C207S mutant.

They catalyze a diversity of mostly two-electron oxidation-reduction reactions crucial in the metabolism of nitrogen, sulfur and carbon.
On the basis of structural, spectroscopic and biochemical characteristics, they have been classified into three broad families named according to well-studied enzymes of each family: xanthine oxidase, sulfite oxidase and DMSO reductase.
