Is nicotinamide adenine dinucleotide phosphate an obligatory intermediate in photosynthesis?
The site of action of the inhibitors disalicylidenepropanediamine and pyrophosphate was more closely defined as acting on ferredoxin. Three inhibitors which act on the electron transport path between ferredoxin and NADP: disalicylidenepropanediamine, pyrophosphate, and phosphoadenosinediphosphate ribose, had no effect on photosynthesis in cell free preparations of Dunaliela parva at concentrati...
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, ...

Microinjection of human Jurkat T-lymphocytes with nicotinic acid adenine dinucleotide phosphate (NAADP 1 ) dose-dependently stimulated intracellular Ca 2 1 -signaling. At a concentration of 10 nM NAADP 1 evoked repetitive and long-lasting Ca 2 1 oscillations of low amplitude, whereas at 50 and 100 nM, a rapid and high initial Ca 2 1 -peak followed by trains of smaller Ca 2 1 -oscillations was o...
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...
