NADP(H) allosterically regulates the interaction between ferredoxin and ferredoxin‐NADP+ reductase [PDF]
FEBS Open Bio, 2019 Ferredoxin‐NADP+ reductase (FNR) in plants receives electrons from ferredoxin (Fd) at the end of the photosynthetic electron transfer chain and converts NADP+ to NADPH. The interaction between Fd and FNR in plants was previously shown to be attenuated by

Inter-Organelle NAD Metabolism Underpinning Light Responsive NADP Dynamics in Plants
Frontiers in Plant Science, 2019 Upon illumination, photosystem I in chloroplasts catalyzes light-driven electron transport from plastocyanin to ferredoxin, followed by the reduction of NADP+ to NADPH by ferredoxin:NADP+ reductase for CO2 fixation.

NADP+ reduction by human lymphocytes [PDF]
Clinical and Experimental Immunology, 1990 SUMMARY The hexose monophosphate shunt (HMPS) is known to be responsible for the reduction of NADP+ by lymphocytes. We tried to find other enzymatic systems that might provide the lymphocytes with NADPH. By measuring the absorbance at 340 nm we noted that the addition of NADP+ to a preparation of disrupted lymphocytes resulted in the ...

Homeostatic regulation of NAD(H) and NADP(H) in cells
Genes and DiseasesNicotinamide adenine dinucleotide (NAD+)/reduced NAD+ (NADH) and nicotinamide adenine dinucleotide phosphate (NADP+)/reduced NADP+ (NADPH) are essential metabolites involved in multiple metabolic pathways and cellular processes.

The regulation and catalytic mechanism of the NADP-malic enzyme from tobacco leaves [PDF]
Journal of the Serbian Chemical Society, 2009 The non-photosynthetic NADP-malic enzyme EC 1.1.1.40 (NADP-ME), which catalyzes the oxidative decarboxylation of L-malate and NADP+ to produce pyruvate and NADPH, respectively, and which could be involved in plant defense responses, was isolated from ...

Adjustment of light-responsive NADP dynamics in chloroplasts by stromal pH
Nature Communications, 2023 Cyclic electron transfer (CET) predominates when NADP+ is at basal levels, early in photosynthetic induction; however, the mechanism underlying the subsequent supply of NADP+ to fully drive steady-state linear electron transfer remains unclear.

NADP(H)-dependent biocatalysis without adding NADP(H)
Proceedings of the National Academy of Sciences, 2022 Isocitrate dehydrogenase 1 (IDH1) naturally copurifies and crystallizes in a resting state with a molecule of its exchangeable cofactor, NADP + /NADPH, bound in each monomer of the homodimer. We report electrochemical studies with IDH1 that exploit this property to reveal the massive advantage of nanoconfinement to ...
