Sources of reducing equivalents for nitrate reductase in Pisum arvense roots
The sources of the nitrate reductase (E.C 1.6.6.1) reducing equivalents were searched for in roots of Pisum arvense by measuring in vivo and in vitro nitrate reductase activity.

Arabidopsis nitrate reductase activity is stimulated by the E3 SUMO ligase AtSIZ1
Small ubiquitin-related modifier (SUMO) is a small polypeptide that modulates protein activity and regulates hormone signalling, abiotic and biotic responses in plants. Here we show that AtSIZ regulates nitrogen assimilation in Arabidopsis through its E3

Non-toxic total nitrogen determination using a low alkaline persulfate digestion
Measuring total nitrogen, nitrate, and nitrite is critical for compliance with water safety standards. Previous methods for measuring total nitrogen were hazardous, time consuming, and expensive.

Influence of lead on N03 uptake and reduction in cucumber seedlings
The influence of PbCl2 on NO3- uptake and activity level of nitrate (NR) and nitrite MR) reductases in cotyledons and roots of cucumber seedlings was studied.

A haloarchaeal ferredoxin electron donor that plays an essential role in nitrate assimilation [PDF]
In the absence of ammonium, many organisms, including the halophilic archaeon Haloferax volcanii DS2 (DM3757), may assimilate inorganic nitrogen from nitrate or nitrite, using a ferredoxin-dependent assimilatory NO3-/NO2- reductase pathway.

Elevated level of cholesterol is positively correlated to prostate cancer development and disease severity. Cholesterol‐lowering drugs, such as statins, are demonstrated to inhibit prostate cancer. VNPP433‐3β interrupts multiple signaling and metabolic pathways, including cholesterol biosynthesis, AR‐mediated transcription of several oncogenes, mRNA 5′

The relationship between redox enzyme activity and electrochemical potential—cellular and mechanistic implications from protein film electrochemistry [PDF]
In protein film electrochemistry a redox protein of interest is studied as an electroactive film adsorbed on an electrode surface. For redox enzymes this configuration allows quantification of the relationship between catalytic activity and ...

Nitrate reductase (NR) is the enzyme that catalyzes the first step of nitrate assimilation. It is well known that the expression of NR genes is rapidly induced in various plants by nitrate.
