A novel cycling assay for nicotinic acid-adenine dinucleotide phosphate with nanomolar sensitivity.
Nicotinic acid-adenine dinucleotide phosphate (NAADP) is a novel nucleotide derived from NADP that has now been shown to be active in releasing Ca(2+) from intracellular stores in a wide variety of cells ranging from plant to human. Despite the obvious importance of monitoring its cellular levels under various physiological conditions, no assay has been reported for NAADP to date. In the presen...
متن کاملSubstituted Nicotinamide Analogues of Nicotinamide Adenine Dinucleotide.
A number of nicotinamide adenine dinucleotide analogues have been prepared in which the purine, pyridine, and ribose moieties have been modified (2-12). These analogues have proven to be valuable in studies dealing with the site of binding of the pyridine coenzyme to dehydrogenases, in elucidating the mechanism of dehydrogenases and the configuration of the pyridme coenzymes, and as indicators ...

متن کاملMeasurement 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, ...
