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.

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.

Other Notes

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

Questions

1–2 of 2 Questions  

  1. How much does 2units weigh?

    1 answer

    1. The amount of solid provided will depend on the enzymatic activity reported on the lot specific Certificate of Analysis. For example, lot SLCR1079 has the enzymatic activity value of 481 units per gram, thus the 2 unit package size would contain roughly 4.16 mg of solid.

      Please view the sample Certificate of Analysis below to see the enzymatic activity:

  2. Guten Tag, benötige ich für die Reaktion denn nicht auch das FAD ?

    1 answer

    1. FAD, Flavin Adenine Dinucleotide, is a component used in determining the activity of Nitrate Reductase. See the link below to review the enzymatic assay protocol:
