Substituted 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 کاملEnzymes of Nuclear Nicotinamide-Adenine Dinucleotide Metabolism
Changing the concentrations of NAD+ and histones did not alter significantly the observed inhibition. However, the inhibition was relieved by increasing amounts of DNA (Fig. 36). The effect of Actinomycin D was further studied by changing the order of addition of the various compounds (Fig. 3c). These results showed that when Actinomycin D was incubated with the polymerase before the addition o...
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, ...
