Glycine dehydrogenase (cyanide-forming)

From Wikipedia, the free encyclopedia

In enzymology, a glycine dehydrogenase (cyanide-forming) (EC 1.4.99.5) is an enzyme that catalyzes the chemical reaction

glycine + 2 A $\rightleftharpoons$ hydrogen cyanide + CO₂ + 2 AH₂

Thus, the two substrates of this enzyme are glycine and A, whereas its 3 products are hydrogen cyanide, CO₂, and AH2.

This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-NH2 group of donors with other acceptors. The systematic name of this enzyme class is glycine:acceptor oxidoreductase (hydrogen-cyanide-forming). Other names in common use include hydrogen cyanide synthase, and HCN synthase.
