Cob(II)yrinic acid a,c-diamide reductase

In enzymology, a cob(II)yrinic acid a,c-diamide reductase is an enzyme that catalyzes the chemical reaction


 * 2 cob(I)yrinic acid a,c-diamide + FMN + 2 H+ $$\rightleftharpoons$$ 2 cob(II)yrinic acid a,c-diamide + FMNH2

The 3 substrates of this enzyme are cob(I)yrinic acid a,c-diamide, FMN, and H+, whereas its two products are cob(II)yrinic acid a,c-diamide and FMNH2.

This enzyme belongs to the family of oxidoreductases, specifically those oxidizing metal ion with a flavin as acceptor. The systematic name of this enzyme class is cob(I)yrinic acid-a,c-diamide:FMN oxidoreductase. This enzyme is also called cob(II)yrinic acid-a,c-diamide:FMN oxidoreductase (incorrect). This enzyme participates in porphyrin and chlorophyll metabolism.
