Regulation of the expression of NADP-malic enzyme by UV-B, red and far-red light in maize seedlings

Brazilian Journal of Medical and Biological Research, 1999
The induction of nicotinamide adenine dinucleotide phosphate-malic enzyme (NADP-ME) in etiolated maize (Zea mays) seedlings by UV-B and UV-A radiation, and different levels of photosynthetically active radiation (PAR, 400-700 nm) was investigated by ...

Antibodies to the glutamate dehydrogenase of Plasmodium falciparum [PDF]

, 1986
Polyclonal antisera raised against Plasmodium knowlesi reacted with NADP-specific glutamate dehydrogenase (GLDH) of P. knowlesi, GLDH of P. falciparum and GLDH of Proteus spp. The antisera did not react with NAD(P) GLDH from bovine liver.

Metabolic changes associated with dark-induced leaf senescence in Arabidopsis nadk2 mutants

Plant Signaling & Behavior, 2023
Arabidopsis NADK2 (NAD kinase 2) is a chloroplast-localized enzyme involved in NADP+ synthesis, which acts as the final electron acceptor in the photosynthetic electron transfer chain.

Aluminium effects on pyridine nucleotide redox state in roots of Scots pine

Acta Societatis Botanicorum Poloniae, 2014
After prolonged (3-9 weeks) hydroponic treatment of Scots pine seedlings with different concentrations (0.5-4.0 mM) of Al (AI(N03)3), the levels of pyridine nucleotides were determined in root homogenates.

Cyclic Electron Flow-Coupled Proton Pumping in Synechocystis sp. PCC6803 Is Dependent upon NADPH Oxidation by the Soluble Isoform of Ferredoxin:NADP-Oxidoreductase

Microorganisms, 2022
Ferredoxin:NADP-oxidoreductase (FNR) catalyzes the reversible exchange of electrons between ferredoxin (Fd) and NADP(H). Reduction of NADP+ by Fd via FNR is essential in the terminal steps of photosynthetic electron transfer, as light-activated electron ...

In planta study of photosynthesis and photorespiration using NADPH and NADH/NAD+ fluorescent protein sensors

Nature Communications, 2020
NADP(H) and NAD(H) are crucial energy molecules in plant metabolism. Here, via the use of circularly permutated fluorescent protein sensors, the authors demonstrate dynamic changes in NADPH and the NADH/NAD+ ratio during photosynthesis and ...

Genome-wide analysis revealed the stepwise origin and functional diversification of HSDs from lower to higher plant species

Frontiers in Plant Science, 2023
Hydroxysteroid dehydrogenase (HSDs) is an oil-body sterol protein (steroleosin) with an NADP(H) binding domain that belongs to the short-chain dehydrogenase/reductase (SDR) superfamily. There are numerous studies on the characterization of HSDs in plants.

Cytosolic NADP-isocitrate dehydrogenase in Arabidopsis leaves and roots

, 2012
NADP-dependent isocitrate dehydrogenase (NADP-ICDH) catalyses the production of NADPH, which is an essential component in the cellular homeostasis. In Arabidopsis, the kinetic parameters (K m and V max) of cytosolic NADP-ICDH were different in leaves and

Structural changes in the recombinant, NADP(H)-binding component of proton translocating transhydrogenase revealed by NMR spectroscopy [PDF]

, 1999
We have analysed 1H, 15N-HSQC spectra of the recombinant, NADP(H)-binding component of transhydrogenase in the context of the emerging three dimensional structure of the protein.
