Identification of the Ferredoxin-Binding Site of a Ferredoxin-Dependent Cyanobacterial Nitrate Reductase [PDF]

Biochemistry, 2017
An in silico model for the 1:1 ferredoxin (Fd)/nitrate reductase (NR) complex, using the known structure of Synechocystis sp. PCC 6803 Fd and the in silico model of Synechococcus sp. PCC 7942 NR, is used to map the interaction sites that define the interface between Fd and NR.

FDX1 Depletion Activates CD8+ T Cell Antitumor Immunity by Promoting DMBT1 Secretion in Cuproptosis of Colorectal Cancer

Cancer Science, EarlyView.
Elesclomol‐induced cuproptosis potently activates both innate and adaptive antitumor immunity, especially CD8+ T cell immunity. FDX1 serves as a central regulator of CD8+ T cell functionality through DMBT1 downregulation during cuproptosis in colorectal cancer.

Prebiotic aqueous reactions catalyzed by native nickel without hydrogen

The FEBS Journal, EarlyView.
Serpentinizing (H2‐producing) hydrothermal vents are candidate environments for metabolic origin. They generate highly reducing conditions that convert CO2 to formate and methane in abiotic reactions resembling reactions of the acetyl‐CoA pathway of CO2 fixation. They also contain natural catalysts. Native nickel (Ni0), like Fe0, Co0, and their alloys,

Design Principles of Plant Thermotolerance: Integrating Photosynthesis, Reproduction, and Field Resilience in a Warming Climate

Plant, Cell &Environment, EarlyView.
ABSTRACT Global food security is increasingly threatened by climate change, as rising temperatures compromise the yields of major staple crops, including wheat, rice, and maize. Enhancing plant thermotolerance has therefore become a critical priority for sustaining agricultural productivity.

A three-domain iron-sulfur flavoprotein obtained through gene fusion of ferredoxin and ferredoxin-NADP+ reductase from spinach leaves

, 1997
Ferredoxin and ferredoxin-NADP+ reductase are the two last partners of the photosynthetic electron-transfer chain, responsible for the final reduction of NADP+ to NADPH.

Exogenous DCPTA Increases the Tolerance of Maize Seedlings to PEG-Simulated Drought by Regulating Nitrogen Metabolism-Related Enzymes

Agronomy, 2019
2-(3,4-Dichlorophenoxy) triethylamine (DCPTA) regulates plant development; however, the molecular basis of this regulation is poorly understood. In this study, RNA sequencing (RNA-seq) analysis and physiological indexes of maize seedlings (three-leaf ...

Ferredoxin and Ferredoxin-NADP Reductase from Photosynthetic and Nonphotosynthetic Tissues of Tomato [PDF]

Plant Physiology, 1991
Ferredoxin and ferredoxin-NADP+ oxidoreductase (FNR) were purified from leaves, roots, and red and green pericarp of tomato (Lycopersicon esculentum, cv VFNT and cv Momotaro). Four different ferredoxins were identified on the basis of N-terminal amino acid sequence and charge.

Multiplexed Nanosensors for Real‐Time Monitoring of VOC‐Mediated Signalling Response in Plants

Plant, Cell &Environment, EarlyView.
ABSTRACT To enhance crop performance, intercropping strategies leverage volatile organic compound (VOC)‐driven interactions with companion plants that constitutively emit VOCs. Despite the agricultural importance, the mechanisms and kinetics of VOC‐mediated sensory transduction in receiver plants eavesdropping on neighbouring non‐kin emitters remain ...
