Nanomechanical Study of Enzyme: Coenzyme Complexes: Bipartite Sites in Plastidic Ferredoxin-NADP⁺ Reductase for the Interaction with NADP⁺

Antioxidants, 2022
Plastidic ferredoxin-NADP+ reductase (FNR) transfers two electrons from two ferredoxin or flavodoxin molecules to NADP+, generating NADPH. The forces holding the Anabaena FNR:NADP+ complex were analyzed by dynamic force spectroscopy, using WT FNR and ...

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.

Auxin is involved in arbuscular mycorrhizal fungi-promoted tomato growth and NADP-malic enzymes expression in continuous cropping substrates

BMC Plant Biology, 2021
Background Despite significant limitations of growth medium reuse, a large amount of organic substrate is reused in soilless cultivation of horticultural crops in China. Arbuscular mycorrhizal fungi (AMF) can promote nutrient absorption and improve plant

NADP+ is an endogenous PARP inhibitor in DNA damage response and tumor suppression

Nature Communications, 2019
Cancer cells respond differently to inhibitors of Poly (ADP-ribose) polymerase. Here the authors reveal that ovarian cancer cells with higher cellular NADP+ levels are more sensitive to clinically relevant PARP1 inhibitors and show that NADP+ act as an ...

NADP-Dependent Isocitrate Dehydrogenase from Arabidopsis Roots Contributes in the Mechanism of Defence against the Nitro-Oxidative Stress Induced by Salinity

The Scientific World Journal, 2012
NADPH regeneration appears to be essential in the mechanism of plant defence against oxidative stress. Plants contain several NADPH-generating dehydrogenases including isocitrate dehydrogenase (NADP-ICDH), glucose-6-phosphate dehydrogenase (G6PDH), 6 ...

Is a Malleable Active Site Loop the Key to High Substrate Promiscuity? Hybrid, Biocatalytic Route to Structurally Diverse Taxoid Side Chains with Remarkable Dual Stereocontrol. [PDF]

Angew Chem Int Ed Engl
A highly stereoselective, dynamic reductive kinetic resolution (DYRKR) entry into myriad Taxotere‐like side chains with Clostridium acetobutylicum alcohol dehydrogenase (CaADH) enzyme is reported. Follow‐on cross couplings expand the structural diversity of the library (36 total examples).

Mitochondrial NADP(H) generation is essential for proline biosynthesis

Science, 2021
Providing for protein synthesis Compartmentalization of metabolic processes into organelles can have important consequences. Zhu et al. examined the role of the coenzyme nicotinamide adenine dinucleotide phosphate (NADP+) and its reduced form (NADPH) in ...

G6PD-mediated increase in de novo NADP+ biosynthesis promotes antioxidant defense and tumor metastasis

Science Advances, 2022
Metastasizing cancer cells are able to withstand high levels of oxidative stress through mechanisms that are poorly understood. Here, we show that under various oxidative stress conditions, pancreatic cancer cells markedly expand NADPH and NADP+ pools ...

Mitochondrial NADP+ is essential for proline biosynthesis during cell growth

Nature Metabolism, 2021
Nicotinamide adenine dinucleotide phosphate (NADP+) is vital to produce NADPH, a principal supplier of reducing power for biosynthesis of macromolecules and protection against oxidative stress.

In Vivo Selection for Formate Dehydrogenases with High Efficiency and Specificity toward NADP+

ACS Catalysis, 2020
The efficient regeneration of cofactors is vital for the establishment of biocatalytic processes. Formate is an ideal electron donor for cofactor regeneration due to its general availability, low reduction potential, and benign byproduct (CO2).
