Webb7 maj 2024 · The nitrite reductases ensure the reduction of nitrite to NO in denitrifying bacteria (denitrification) and into ammonium in DNRA bacteria, also known as ammonifiers (see below). In denitrifying bacteria, two types of unrelated nitrite reductases (Nir) have been identified so far (reviewed in Moura and Moura, 2001 ). Webb23 dec. 2014 · Nitrite reductase (NiR) is a critical enzyme involved in nitrogen metabolism in plants. A full-length cDNA sequence of 1,764 bp for the NiR gene was isolated from … lma 5020
nirA, the Pathway-Specific Regulatory Gene of Nitrate …
Nitrate reductase (NR) is regulated at the transcriptional and translational levels induced by light, nitrate, and possibly a negative feedback mechanism. First, nitrate assimilation is initiated by the uptake of nitrate from the root system, reduced to nitrite by nitrate reductase, and then nitrite is reduced to ammonia … Visa mer Nitrate reductases are molybdoenzymes that reduce nitrate (NO 3) to nitrite (NO 2). This reaction is critical for the production of protein in most crop plants, as nitrate is the predominant source of nitrogen in fertilized soils. Visa mer Eukaryotic Eukaryotic nitrate reductases are part of the sulfite oxidase family of molybdoenzymes. … Visa mer In prokaryotic periplasmic nitrate reductase, the nitrate anion binds to Mo(IV). Oxygen transfer yields an Mo(VI) oxo intermediate … Visa mer • UMich Orientation of Proteins in Membranes protein/pdbid-1q16 • Nitrate+reductases at the U.S. National Library of Medicine Medical Subject Headings (MeSH) Visa mer Prokaryotic nitrate reductases have two major types, transmembrane nitrate reductases and periplasmic nitrate reductases. The transmembrane nitrate reductase (NAR) … Visa mer Nitrate reductase activity can be used as a biochemical tool for predicting grain yield and grain protein production. Nitrate reductase … Visa mer Webb15 nov. 2007 · PPT-resistance of transformants disappears when they are transferred from nitrate-containing medium to ammonium-containing medium. The findings of this study … WebbThus, the regulation of expression of tobacco NiR genes is comparable to the regulation of expression of barley NR genes. Three tobacco nitrite reductase (NiR) cDNA clones were isolated using spinach NiR cDNA as a probe and sequence analysis and Southern blot hybridization revealed four genes in tobacco that are comparable to barley NR genes. casa janela
