Pyridine nucleotidenitrate reductase from Hansenula anomala a nitrate reducing yeast.
The recent elucidation of the enzyme systems involved in nitrate reduction in Neurospora crassa (Evans and Nason, 1952; Nason and Evans, 1953); Bacillus pumilis (Taniguchi et al., 1953); Escherichia coli (Taniguchi et al., 1956; Nicholas and Nason, 1955) and higher plants (Evans and Nason, 1953), has renewed interest in the general problem of nitrate reduction and nitrate assimilation in microo...
متن کاملPyridine nucleotide specificity of barley nitrate reductase.
NADPH nitrate reductase activity in higher plants has been attributed to the presence of NAD(P)H bispecific nitrate reductases and to the presence of phosphatases capable of hydrolyzing NADPH to NADH. To determine which of these conditions exist in barley (Hordeum vulgare L. cv. Steptoe), we characterized the NADH and NADPH nitrate reductase activities in crude and affinity-chromatography-purif...
متن کاملNitrite causes reversible inactivation of nitrate reductase in the yeast Hansenula anomala.
The addition of nitrite, the product of the reaction catalysed by nitrate reductase, to cell suspensions of the yeast Hansenula anomala caused a reversible inactivation of NADPH-dependent nitrate reductase activity. The haem- and Mo-dependent and Mo-dependent activities of nitrate reductase, determined with the non-physiological electron donors FMNH2 and reduced methyl viologen respectively, we...
متن کاملNitrite causes reversible inactivation of nitrate reductase in the yeast Hansenula anornala
Laguna, Tenerife, Canarias, Spain haemand Mo-dependent and Mo-dependent activities of nitrate reductase, determined with the non-physiological electron donors FMNH, and reduced methyl viologen respectively, were less affected. A similar inactivation was found with the proton ionophores 2,rddinitrophenol and carbonyl cyanide m-chlorophenylhydrazone. The inactive enzyme was found in the particula...
متن کاملAnalysis of nitrate reductase mRNA expression and nitrate reductase activity in response to nitrogen supply
Nitrate is one of the major sources of nitrogen for the growth of plants. It is taken up by plant roots and transported to the leaves where it is reduced to nitrite in the. The main objective of this research was to investigate stimulatory effects of sodium nitrate, potassium nitrate, ammonia and urea on the production/generation of the nitrate reductase mRNA in Triticum aestivum plants. The pl...
