 Sulfite dehydrogenase

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

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.
