In enzymology, a sulfite dehydrogenase (EC 1.8.2.1) is an enzyme that catalyzes the chemical reaction

sulfite + 2 ferricytochrome c + H2O sulfate + 2 ferrocytochrome c + 2 H+

The 3 substrates of this enzyme are sulfite, ferricytochrome c, and H2O, whereas its 3 products are sulfate, ferrocytochrome c, and H+.

This enzyme belongs to the family of oxidoreductases, specifically those acting on a sulfur group of donor with a cytochrome as acceptor. The systematic name of this enzyme class is sulfite:ferricytochrome-c oxidoreductase. Other names in common use include sulfite cytochrome c reductase, sulfite-cytochrome c oxidoreductase, and sulfite oxidase. This enzyme participates in sulfur metabolism.

Cytochrome b<sub>5</sub>

Cytochromes b5 are ubiquitous electron transport hemoproteins found in animals, plants, fungi and purple phototrophic bacteria. The microsomal and mitochondrial variants are membrane-bound, while bacterial and those from erythrocytes and other animal tissues are water-soluble. The family of cytochrome b5-like proteins includes hemoprotein domains covalently associated with other redox domains in flavocytochrome cytochrome b2, sulfite oxidase, plant and fungal nitrate reductases, and plant and fungal cytochrome b5/acyl lipid desaturase fusion proteins.
