L-ascorbate-cytochrome-b5 reductase

In enzymology, a L-ascorbate---cytochrome-b5 reductase is an enzyme that catalyzes the chemical reaction


 * L-ascorbate + ferricytochrome b5 $$\rightleftharpoons$$ monodehydroascorbate + ferrocytochrome b5 + H+

Thus, the two substrates of this enzyme are L-ascorbate and ferricytochrome b5, whereas its 3 products are monodehydroascorbate, ferrocytochrome b5, and H+.

This enzyme belongs to the family of oxidoreductases, specifically those acting on diphenols and related substances as donor with a cytochrome as acceptor. The systematic name of this enzyme class is L-ascorbate:ferricytochrome-b5 oxidoreductase. This enzyme is also called ascorbate-cytochrome b5 reductase.
