In enzymology a pyruvate dehydrogenase (cytochrome) (EC 1.2.2.2) is an enzyme that catalyzes the chemical reactionpyruvate + ferricytochrome b1 + H2O acetate + CO2 + ferrocytochrome b1The 3 substrates of this enzyme are pyruvate ferricytochrome b1 and H2O whereas its 3 products are acetate CO2 and ferrocytochrome b1.This enzyme belongs to the family of oxidoreductases specifically those acting on the aldehyde or oxo group of donor with a cytochrome as acceptor.
