Nitrogen assimilation and nitrogen control in cyanobacteria
Biochemical Society Transactions, 2005Nitrogen sources commonly used by cyanobacteria include ammonium, nitrate, nitrite, urea and atmospheric N2, and some cyanobacteria can also assimilate arginine or glutamine. ABC (ATP-binding cassette)-type permeases are involved in the uptake of nitrate/nitrite, urea and most amino acids, whereas secondary transporters take up ammonium and, in some ...

Nitrogen assimilation in Rhodopseudomonas acidophila
Archives of Microbiology, 1978Rhodopseudomonas acidophila strain 7050 assimilated ammonia via a constitutive glutamine synthetase/glutamate synthase enzyme system. Glutamine synthetase had a Km for NH+4 of 0.38 mM whilst the nicotinamide adenine dinucleotide linked glutamate synthase had a Km for glutamine of 0.55 mM. R.

Nitrogen Assimilation and Dissimilation
2021Nitrogen is an important element of Earth’s atmosphere and exists in both inorganic and organic forms. In nature, one form is to another through various biological and physical processes. The major steps involved in the cycling of nitrogen are nitrogen fixation, ammonification, nitrification, denitrification and anammox catalyzed by variety of microbes.

Nitrogen Assimilation in Grapevine
2001Nitrogen plays the most important role of all nutrients in plant growth. It is the plant nutrient most likely to be deficient in grapevine although it is the nutrient most commonly applied to vineyards to increase productivity. Considerable new information has been obtained over the past twenty years on the uptake, translocation, distribution ...

Plant Nitrogen Assimilation and Use Efficiency
Annual Review of Plant Biology, 2012Crop productivity relies heavily on nitrogen (N) fertilization. Production and application of N fertilizers consume huge amounts of energy, and excess is detrimental to the environment; therefore, increasing plant N use efficiency (NUE) is essential for the development of sustainable agriculture.

Uptake and assimilation of nitrogen by marine diatoms—II. Kinetics of nitrogen assimilation
Proceedings / Indian Academy of Sciences, 1988A comparison ofK M values for nitrate and nitrite reductases with uptake capacities of 6 marine diatoms indicated that intracellular accumulation of NO 3 − and NO 2 − is necessary for ...
