 Cytochrome-c3 hydrogenase

In enzymology, a cytochrome-c3 hydrogenase () is an enzyme that catalyzes the chemical reaction

Thus, the two substrates of this enzyme are H2 and ferricytochrome c3, whereas its two products are H+ and ferrocytochrome c3.This enzyme belongs to the family of oxidoreductases, specifically those acting on hydrogen as donor with a cytochrome as acceptor.
