Application

Nitrate reductase from Arabidopsis thaliana has been used in a study to assess the amino acid sequence of chicken hepatic sulfite oxidase.
Catalyzes the NADH-dependent reduction of nitrate to nitrite.

Biochem/physiol Actions

Nitrate reductase activity is induced in Arabidopsis thaliana plants by sumoylation via the E3 ligase activity of AtSIZ1.

Unit Definition

One unit will reduce 1.0 micromole of nitrate to nitrite per min in a NADH system at pH 7.5 at 30 deg C.

Physical form

Supplied as a lyophilized powder containing 50 mM MOPS, pH 7.0, 0.1 mM EDTA and a proprietary sugar

Acetogenic bacteria grow by the oxidation of various substrates coupled to the reduction of carbon dioxide (acetogenesis) or other electron acceptors but the mechanisms of energy conservation are still enigmatic. Here, we report the presence of a rnf gene cluster

The activity of nitrate reductase (+Mg(2+), NR(act)) in illuminated leaves from spinach, barley and pea was 50-80% of the maximum activity (+EDTA, NR(max)). However, NR from leaves of Ricinus communis L. had a 10-fold lower NR(act), while NR(max) was similar

The mechanism of the post-translational modulation of nitrate reductase activity (NR, EC 1.6.6.1) is briefly summarized, and it is shown that by this mechanism nitric oxide production through NR is also rapidly modulated. New and partly unexpected details on the
