The fractions were analyzed by western blotting, and GAPDH or COX-IV was used as the cytosolic or mitochondrial loading control, respectively. 2.9. Hexokinase (HK) activity detection The HK activity assay is based on the reduction of NADP+ to NADPH, through a coupled reaction with glucose-6-...
TNT hydrolyzed the dinucleotides NAD+ and NADP+ but not their reduced forms NADH and NADPH (Fig. 2B). Addition of the antitoxin IFT prevented hydrolysis of both NAD+ and NADP+ (Fig. 2C). This result indicates that both dinucleotides are cleaved at the same site because IFT blocks access ...
The central feature of this process is the development of a cartilage template, known as the growth plate, which drives longitudinal growth through chondrocyte proliferation, hypertrophy, and ultimately differentiation into osteoblasts1,2,3,4,5,6,7,8. The timing of the transition from proliferation ...
When a sufficient amount of coen- zyme (reduced nicotinamide adenine dinucleotide phosphate, NADPH) was added to the extraction me- dium, the activity of isocitric dehydrogenase (EC. 1.1.1.42) was normal. In contrast, absence of the coenzyme was associated with diminished activity of isocitric ...
Nonetheless, only NADPH, not NADH, is generated in the anaerobic E. gracilis mitochondria, because the oxidative decarboxylation of pyruvate is catalysed by pyruvate:NADP+ oxidoreductase instead of common pyruvate dehydrogenase multienzyme complex (NAD+-dependent) [[5]]. Thus, we aimed to clarify...
Reduced labeling of PRDX6 by TAMRA-FP identifies PLA2 inhibitors that bind PRDX6. See also Figure S2C. (B) Inhibition of P. falciparum ring-to-schizont progression and blood-stage growth with PLA2 inhibitors. Parasites were treated at ring ...

, 2012). In plant cells, peroxisomes house a large number of antioxidative enzymes, such as catalase, superoxide dismutase, components of the ascorbate–glutathione cycle and several NADP dehydrogenases (Corpas et al., 2001). Moreover, the production of superoxide radicals has also been reported ...
The native protein is bright yellow and contains noncovalently attached FAD that is reduced by either dithionite or NADPH without formation of a stable semiquinone. Titration with NADP+/NADPH gives an E0' value of approximately -327 mV versus SHE. Because this E0' is so close to that of the...
coli transhydrogenase 11, 12showed that it is cyclic (NADP+ and NADPH remain tightly bound to domain III of the enzyme, while being alternately reduced and oxidized by NADH and AcPdAD+ located on domain I, see Fig. 1). There are some differences in the character of the cyclic reaction ...
