Feedback regulation of photosynthetic electron transport by NADP(H) redox poise

Biochimica et Biophysica Acta (BBA) - Bioenergetics, 2008
When plants experience an imbalance between the absorption of light energy and the use of that energy to drive metabolism, they are liable to suffer from oxidative stress. Such imbalances arise due to environmental conditions (e.g.

NAD(H) and NADP(H) in plants and mammals.

Mol Plant
Nicotinamide adenine dinucleotide (NAD) and nicotinamide adenine dinucleotide phosphate (NADP) are essential metabolic coenzymes in prokaryotic and eukaryotic cells, with their reduced forms, NAD(P)H, serving as electron donors for myriad reactions.

Building Localized NADP(H) Recycling Circuits to Advance Enzyme Cascadetronics. [PDF]

Angew Chem Int Ed Engl
Abstract The catalytic action of enzymes in a cascade trapped within a mesoporous electrode material is simultaneously energized, controlled and observed through the efficient, reversible electrochemical NAD(P)(H) recycling catalyzed by one of the enzymes.

Identification of CCR4C as a chloroplast-localized NADP(H) phosphatase regulating NAD(P)(H) balance in <i>Arabidopsis</i>. [PDF]

Proc Natl Acad Sci U S A
NAD(P)(H) metabolism plays a crucial role in plant development and growth. NADK2, a chloroplast-localized NAD kinase, supplies NADP + to the photosynthetic electron transport chain. The Arabidopsis T-DNA insertion mutant of NADK2 ( nadk2 ) exhibits a reduced NADP

Molecular properties and regulation of NAD+ kinase (NADK)

Redox Biology, 2023
Nicotinamide adenine dinucleotide (NAD+) kinase (NADK) phosphorylates NAD+, thereby producing nicotinamide adenine dinucleotide phosphate (NADP). Both NADK genes and the NADP(H)-producing mechanism are evolutionarily conserved among archaea, bacteria ...

Atmospheric deposition of mercury and major ions to the Pensacola (Florida) watershed: spatial, seasonal, and inter-annual variability [PDF]

Atmospheric Chemistry and Physics, 2010
Atmospheric deposition was measured at three sites in the Pensacola Bay watershed, Florida, between November 2004 and December 2007. Mercury deposition in the Pensacola Bay watershed was similar to that from nearby Mercury Deposition Network sites along ...
