Flavodiiron proteins associate pH‐dependently with the thylakoid membrane for ferredoxin‐1‐powered O2 photoreduction

New Phytologist, Volume 246, Issue 5, Page 2084-2101, June 2025.
Summary Flavodiiron proteins (FDPs) catalyse light‐dependent reduction of oxygen to water in photosynthetic organisms, creating an electron sink on the acceptor side of Photosystem I that protects the photosynthetic apparatus. However, ambiguity about the electron donor(s) remains, and the molecular mechanisms regulating FDP activity have remained ...

Elucidating the enzyme network driving Amaryllidaceae alkaloids biosynthesis in Leucojum aestivum

Plant Biotechnology Journal, Volume 23, Issue 6, Page 1988-2005, June 2025.
Schematic representation of Amaryllidaceae alkaloid biosynthesis in Leucojum aestivum. Norbelladine synthase (LaNBS) and noroxomaritidine/norcraugsodine reductase (LaNRII) catalyze the condensation of tyramine and 3,4‐dihydroxybenzaldehyde to form norbelladine, which is subsequently O‐methylated by norbelladine‐4′‐O‐methyltransferase (LaN4′OMT ...

Stomata‐Photosynthesis Synergy Mediates Combined Heat and Salt Stress Tolerance in Sugarcane Mutant M4209

Plant, Cell &Environment, Volume 48, Issue 6, Page 4668-4684, June 2025.
ABSTRACT Sugarcane (Saccharum officinarum L.) is an economically important long‐duration crop which is currently facing concurrent heat waves and soil salinity. The present study evaluates an inducible salt‐tolerant sugarcane mutant M4209, developed via radiation‐induced mutagenesis of elite check variety Co 86032, under heat (42/30°C; day/night), NaCl

NADP regulates the light activation of NADP-dependent malate dehydrogenase

Planta, 1983
The chloroplastic NADP-dependent malate-dehydrogenase (EC 1.1.1.82) activity is modulated by light and dark. The enzyme is activated upon illumination of intact or broken chloroplasts or by incubation with dithiothreitol, whereas dark has the opposite effect.

Binding of NAD and NADP dimers to NAD- and NADP-dependent dehydrogenases

Biochimica et Biophysica Acta (BBA) - Protein Structure and Molecular Enzymology, 1984
Interaction of the electrolytically prepared dimers of nicotinamide adenine nucleotide, (NAD)2, and nicotinamide adenine nucleotide phosphate, (NADP)2, with lactate, alcohol, glyceraldehyde 3-phosphate, alpha-glycerophosphate, glutamate and glucose-6-phosphate dehydrogenase has been studied using the quenching of protein fluorescence, kinetics of ...

Thio-NADP is not an antagonist of NAADP

Cell Biochemistry and Biophysics, 1998
Nicotinic acid adenine dinucleotide phosphate (NAADP) is a metabolite of NADP, which can release Ca2+ from stores that are distinct from those activated by either cyclic ADP-ribose or inositol 1,4,5-trisphosphate (IP3). It has previously been suggested that thio-NADP is a specific antagonist of NAADP (Chini et al. [1995] J. Biol. Chem. 270, 3216-3223).

Photoreduction of NAD and NADP by chlorophyllin a in the presence of ascorbate: Requirement for NADP reductase

Archives of Biochemistry and Biophysics, 1965
Abstract Chlorophyllin a catalyzes the photoreduction of NADP (and NAD to a lesser extent) in the presence of ascorbate as electron donor and NADP reductase as the coupling enzyme. Photosynthetic pyridine nucleotide reductase is inactive in the reaction and does not stimulate the reaction observed with NADP reductase.

The Synthesis of Poly-L-Lysine-Succinyl-Nadp: An Analogue for Nadp/H

The International Journal of Artificial Organs, 1980
Poly-L-lysine-succinyl-NADP, an analogue for nicotinamide adenine dinucleotide phosphate (NADP/H), has been synthesized by linking NADP/H to poly-L-lysine hydrobromide. This analogue (PL-SNP) was assayed with N, N dimethylaniline (DMA) in the presence of hepatic microsomal oxidase. A regeneration system of G-6-p and G-6-PD was used for reducing the PL-

Apollo-NADP+: a spectrally tunable family of genetically encoded sensors for NADP+

Nature Methods, 2016
NADPH-dependent antioxidant pathways have a critical role in scavenging hydrogen peroxide (H2O2) produced by oxidative phosphorylation. Inadequate scavenging results in H2O2 accumulation and can cause disease. To measure NADPH/NADP(+) redox states, we explored genetically encoded sensors based on steady-state fluorescence anisotropy due to FRET ...
