Opis ogólny
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.
Działania biochem./fizjol.
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.
Przestroga
light and moisture sensitive
Definicja jednostki
One unit will reduce 1.0 μmole of nitrate per min in the presence of β-NADPH at pH 7.5 at 25 °C.

Ragweed extract (RWE) contains NADPH oxidases that induce oxidative stress in the airways independent of adaptive immunity (signal 1) and augment antigen (signal 2)-induced allergic airway inflammation. To test whether inhibiting signal 1 by administering antioxidants inhibits allergic airway inflammation

Nitric oxide (NO) is a free radical involved in inflammation and immune reactions. The presence of NO is usually assessed by assaying its degradation products, nitrite and nitrate. NO binds to thiol-containing proteins to form S-nitrosoproteins (S-NP). The aim of

In vitro complementation of the soluble assimilatory NAD(P)H-nitrate reductase (NAD(P)H:nitrate oxidoreductase, EC 1.6.6.2) was attained by mixing cell-free preparations of Chlamydomonas reinhardii mutant 104, uniquely possessing nitrate-inducible NAD(P)H-cytochrome c reductase, and mutant 305 which possesses solely the nitrate-inducible FMNH2- and

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.
