In enzymology a cytochrome-c3 hydrogenase (EC 1.12.2.1) is an enzyme that catalyzes the chemical reaction2 H2 + ferricytochrome c3 4 H+ + ferrocytochrome c3Thus 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.
