Measurement of nicotinamide adenine dinucleotide & nicotinamide adenine dinucleotide phosphate in tomato leaves.
As part of an investigation of the growth of tomato plants supplied with either nitrate or ammonium nitrogen (6), leaves were assayed for NAD4 and NADP. Anderson and Vennesland (1) assayed NAD and NADP in various green tissues and reported recoveries between 50 % and 85 % of NAD and NADP added to spinach leaf extracts. Very low levels of NAD and NADP were recorded for tomato leaf extracts. Thes...
متن کاملInhibition of rat liver nicotinamide adenine dinucleotide kinase by reduced nicotinamide adenine dinucleotide phosphate.
Rat liver NAD kinase (ATP : NAD 2’-phosphotransferase, EC 2.7.1.23) was purified about 70-fold. The MichaelisMenten constants (Km) for NAD and ATP were 8 x 10e4 M and 2 x low3 M, respectively. NAD kinase activity was markedly inhibited by NADH and also NADPH. The Ki of NADH was approximately 1 X 10q4 M, and that of NADPH was approximately 5 X 10M5 M. Both inhibitions were competitive with NAD, ...
متن کاملNicotinamide Adenine Dinucleotide Phosphate - specific Isocitrate
Nicotiniamide adenine dintucleotide plhosphate-specific isocitrate dehydrogenase was extracted from etiolated pea (Pisurn satirum L.) seedlings and was purified 65-fold. The puirified enzyme exhibits one predoniinant protein band by pol acrylamide gel electrophoresis, w-hich corresponds to tiie dehy-drogenase activity as imieasuired by the nitro bluie tetrazolium technique. The reaction is read...
متن کاملApocynin Is Not an Inhibitor of Vascular Reduced Nicotinamide-Adenine Dinucleotide Phosphate Oxidases But an Antioxidant
A large body of literature suggest that vascular reduced nicotinamide-adenine dinucleotide phosphate (NADPH) oxidases are important sources of reactive oxygen species. Many studies, however, relied on data obtained with the inhibitor apocynin (4 -hydroxy-3 methoxyacetophenone). Because the mode of action of apocynin, however, is elusive, we determined its mechanism of inhibition on vascular NAD...
متن کاملRegulation of the nicotinamide adenine dinucleotide- and nicotinamide adenine dinucleotide phosphate-dependent glutamate dehydrogenases of Saccharomyces cerevisiae.
Saccharomyces cerevisiae contains two distinct l-glutamate dehydrogenases. These enzymes are affected in a reciprocal fashion by growth on ammonia or dicarboxylic amino acids as the nitrogen source. The specific activity of the nicotinamide adenine dinucleotide phosphate (NADP) (anabolic) enzyme is highest in ammonia-grown cells and is reduced in cells grown on glutamate or aspartate. Conversel...
