Claim: Leghemoglobin reductase, also called ferric leghemoglobin reductase, is an enzyme  that is similar to NADH as it catalyzes the chemical reaction wherein it was purified by scientists in 1982 from lupine nodules which catalyzed the reduction of Lb to Lb using NADH as reductant.
Evidence: In 1982 Kretovich and collaborators purified an enzyme from lupine nodules which catalyzed the reduction of Lb to Lb using NADH as reductant. This enzyme is also called ferric leghemoglobin reductase. This enzyme (named by these authors as Legoglobin Reductase -LR) is similar to NADH:cytochrome b5 reductase (EC 1.6.2.2) from erythrocytes and bovine muscle.
