Cyanocobalamin reductase (cyanide-eliminating)
In enzymology, a cyanocobalamin reductase is an enzyme that catalyzes the chemical reaction
The 3 substrates of this enzyme are cobalamin, cyanide, and NADP+, whereas its 3 products are cyanocobalamin, NADPH, and H+.
This enzyme belongs to the family of oxidoreductases, specifically those that oxidize metal ions and use NAD+ or NADP+ as an electron acceptor. The systematic name of this enzyme class is cobalamin, cyanide:NADP+ oxidoreductase. Other names in common use include cyanocobalamin reductase, cyanocobalamin reductase , cyanocobalamin reductase , and NADPH:cyanocobalamin oxidoreductase . This enzyme participates in porphyrin and chlorophyll metabolism. It uses one cofactor, FAD.
