Claim: Leghemoglobin reductase, an enzyme similar to NADH, was purified by Kretovish and collaborators in 1982 from lupine nodules which catalyzed the reduction of Lb to Lb using NADH as reductant.
Evidence: This enzyme belongs to the family of oxidoreductases, specifically those acting on NADH or NADPH with a heme protein as acceptor. In 1982 Kretovich and collaborators purified an enzyme from lupine nodules which catalyzed the reduction of Lb to Lb using NADH as reductant. The systematic name of this enzyme class is NAD(P)H:ferrileghemoglobin oxidoreductase.
