General description

Nitrate reductase (NAD[P]H) is expressed in variety of organisms including bacteria, fungi, algae, and higher plants which have capacity to use nitrate as their sole source of nitrogen.Experimental studies show that nitrate reductase (NAD[P]H) is 180,000Daltons.[1]

Biochem/physiol Actions

Nitrate Reductase (NAD[P]H) catalyzes the reduction of nitrate to nitrite. In addition, it also catalyzes the reduction of NADPH-cytochrome c, FADH2-nitrate. Nitrate reductase also has reduced methyl viologen-nitrate reductase activities.[1]

Caution

light and moisture sensitive

Unit Definition

One unit will reduce 1.0 μmole of nitrate per min in the presence of β-NADPH at pH 7.5 at 25 °C.

Barley (Hordeum vulgare L.) has NADH-specific and NAD(P)H-bispecific nitrate reductase isozymes. Four isogenic lines with different nitrate reductase isozyme combinations were used to determine the role of NADH and NAD(P)H nitrate reductases on nitrate transport and assimilation in barley seedlings.
