Nitrate reductase - Wikipedia
Eukaryotic nitrate reductases are part of the sulfite oxidase family of molybdoenzymes. They transfer electrons from NADH or NADPH to nitrate.
Structural and mechanistic insights on nitrate reductases
Nitrate reductases (NR) belong to the DMSO reductase family of Mo‐containing enzymes and perform key roles in the metabolism of the nitrogen cycle, reducing nitrate to nitrite. Due to variable cell location, structure and function, they have been ...
Nitrate Reductase - an overview | ScienceDirect Topics
Nitrate reductase is a key enzyme in nitrogen assimilation, and it catalyzes the nitrate-to-nitrite reduction process in plants. A variety of factors, including nitrate, light, metabolites, phytohormones, low temperature, and drought, modulate the expression levels of nitrate reductase genes as well as nitrate reductase activity, which is ...
NITRATE REDUCTASE STRUCTURE, FUNCTION AND …
Nitrate reductase (NR; EC 1.6.6.1-3) catalyzes NAD(P)H reduction of nitrate to nitrite. NR serves plants, algae, and fungi as a central point for integration of metabolism by governing flux of reduced nitrogen by several regulatory mechanisms.
Nitrate and periplasmic nitrate reductases - PMC - PubMed …
Classified into three distinct types – periplasmic nitrate reductase (Nap), respiratory nitrate reductase (Nar) and assimilatory nitrate reductase (Nas), they are defined by their cellular location, operon organization and active site structure.
Nitrate Reductase - an overview | ScienceDirect Topics
Nitrate reductase is an enzyme that catalyze the conversion of nitrate to nitrite. For example, Zn 2+ bioreduction is initiated by electron transfer from NADH by NADH-dependent reductase that acts as electron carrier.
Prokaryotic Nitrate Reduction: Molecular Properties and …
Nitrate reduction can be performed with three different purposes: the utilization of nitrate as a nitrogen source for growth (nitrate assimilation), the generation of metabolic energy by using nitrate as a terminal electron acceptor (nitrate respiration), and the dissipation of excess reducing power for redox balancing (nitrate dissimilation).
