Nitrate reductase nadh
WebbNitrate reductase (NR) is capable of utilizing the reduced form of pyridine nucleotides, flavins or benzyl viologen as electron donors for reduction of nitrate to nitrite. NADH-dependent nitrate reductase is most prevalent in plants. Hence, NR activity in plants can be measured by following the oxidation of NAD (P)H at 340nm. Webb21 feb. 1974 · The nitrate-reducing component may be studied separately from the diaphorase component by substituting certain artificial electron donors such as reduced …
