Regulation of photosynthetic electron flow on dark to light transition by ferredoxin:NADP(H) oxidoreductase interactions

open access: yeseLife, 2021
During photosynthesis, electron transport is necessary for carbon assimilation and must be regulated to minimize free radical damage. There is a longstanding controversy over the role of a critical enzyme in this process (ferredoxin:NADP(H ...

Ferredoxin binding site on ferredoxin: NADP+ reductase [PDF]

open access: yesEuropean Journal of Biochemistry, 1993
The chloroplast enzyme ferredoxin:NADP+ reductase (FNR) catalyzes the reduction of NADP+ by ferredoxin (Fd). FNR and Fd form a 1:1 complex that is stabilized by electrostatic interactions between acidic residues of Fd and basic residues of FNR. To localize lysine residues at the Fd binding site of FNR, the FNR:Fd complex (both proteins from spinach ...

Oxidation of P700 Induces Alternative Electron Flow in Photosystem I in Wheat Leaves

open access: yesPlants, 2019
Oxygen (O2)-evolving photosynthetic organisms oxidize the reaction center chlorophyll, P700, in photosystem I (PSI) to suppress the production of reactive oxygen species.

The oxidoreductase activity of Rnf balances redox cofactors during fermentation of glucose to propionate in Prevotella

open access: yesScientific Reports, 2023
Propionate is a microbial metabolite formed in the gastrointestinal tract, and it affects host physiology as a source of energy and signaling molecule. Despite the importance of propionate, the biochemical pathways responsible for its formation are not ...

Variable protection against experimental broiler necrotic enteritis after immunisation with the C-terminal fragment of Clostridium perfringens alpha-toxin and a non-toxic NetB variant [PDF]

open access: yes, 2016
Necrotic enteritis toxin B (NetB) is a pore-forming toxin produced by Clostridium perfringens and has been shown to play a key role in avian necrotic enteritis (NE), a disease causing significant costs to the poultry production industry worldwide.

Photosynthesis under far‐red light—evolutionary adaptations and bioengineering of light‐harvesting complexes

open access: yesFEBS Letters, EarlyView.
Phototrophs evolved light‐harvesting systems adapted for efficient photon capture in habitats enriched in far‐red radiation. A subset of eukaryotic pigment‐binding proteins can absorb far‐red photons via low‐energy chlorophyll states known as red forms.

Aerobic Barley Mg-protoporphyrin IX Monomethyl Ester Cyclase is Powered by Electrons from Ferredoxin

open access: yesPlants, 2020
Chlorophyll is the light-harvesting molecule central to the process of photosynthesis. Chlorophyll is synthesized through 15 enzymatic steps. Most of the reactions have been characterized using recombinant proteins.

NsrR from Streptomyces coelicolor is a nitric oxide-sensing [4Fe-4S] cluster protein with a specialized regulatory function [PDF]

open access: yes, 2015
The Rrf2 family transcription factor NsrR controls expression of genes in a wide range of bacteria in response to nitric oxide (NO). The precise form of the NO-sensing module of NsrR is the subject of controversy because NsrR proteins containing either ...
