Nitrate reductase (NR), the first enzyme in the nitrate assimilation pathway, is regulated post-
transcriptionally in response to light and CO2. In spinach, it has been shown that …

Nitrate reductase (NR) is rapidly inactivated by phosphorylation of serine residues in
response to loss of light or reduction in CO2 levels. To identify sites within NR protein that …

Mutant plants defective in the assimilation of nitrate can be selected by their resistance to the
herbicide chlorate. In Arabidopsis thaliana, mutations at any one of nine distinct loci confer …

Recombinant Arabidopsis thaliana NADH: nitrate reductase (NR; EC 1.6. 6.1) was produced
in the methylotrophic yeast Pichia pastoris and purified to near-electrophoretic homogeneity …

NR (EC 1.6. 6.1-3) was first isolated and characterized more than 40 years ago, and each
decade of study of this key enzyme of nitrate assimilation has been associated with a new …

Purified nitrate reductase (NR) from spinach leaves was phosphorylated in vitro by NR‐
inactivating kinase on Ser‐543 which is located in the hinge 1 region between the …

Spinach leaf NADH: nitrate reductase (NR) responds to light/dark signals and photosynthetic
activity in part as a result of rapid regulation by reversible protein phosphorylation. We have …

Two types of nitrate reductase (NR) have been recognized in higher plants. Most plants
contain a NADH‐specific NR, a few plants contain only a NAD (P) H‐bispecific NR and …

Higher plant nitrate reductases (NRs) carry an N-terminal domain whose sequence is not
conserved in NRs from other organisms. A gene composed of a full-length tobacco NR …

Nitrate assimilation is the primary pathway through which most reduced nitrogen is
accumulated in plants. The pathway consists of two well characterized enzymes, nitrate and …
