In enzymology, a leghemoglobin reductase (EC 126.96.36.199) is an enzyme that catalyzes the chemical reaction
- NAD(P)H + H+ + 2 ferrileghemoglobin NAD(P)+ + 2 ferroleghemoglobin
This enzyme belongs to the family of oxidoreductases, specifically those acting on NADH or NADPH with a heme protein as acceptor. The systematic name of this enzyme class is NAD(P)H:ferrileghemoglobin oxidoreductase. This enzyme is also called ferric leghemoglobin reductase.
