Responses of the marine diatom Thalassiosira pseudonana to changes in CO2 concentration: a proteomic approach [PDF]

, 2017
The concentration of CO2 in many aquatic systems is variable, often lower than the KM of the primary carboxylating enzyme Rubisco, and in order to photosynthesize efficiently, many algae operate a facultative CO2 concentrating mechanism (CCM).

Electron transport phosphorylation in rumen butyrivibrios: unprecedented ATP yield for glucose fermentation to butyrate. [PDF]

, 2015
From a genomic analysis of rumen butyrivibrios (Butyrivibrio and Pseudobutyrivibrio sp.), we have re-evaluated the contribution of electron transport phosphorylation (ETP) to ATP formation in this group.

Characterisation of components and mechanisms involved in redox-regulation of protein import into chloroplasts [PDF]

, 2009
The vast majority of chloroplast proteins is encoded in the nucleus and thus has to be posttranslationally imported into the organelle, a process that is facilitated by two multimeric protein machineries, the Toc and Tic complexes (translocon at the ...

Phycocyanobilin biosynthesis in Galdieria sulphuraria requires isomerization of phycoerythrobilin synthesized by bilin reductases

The FEBS Journal, EarlyView.
The biosynthesis of bilins, tetrapyrroles essential for light harvesting and sensing, is performed by specific enzymes (FDBRs). In Galdieria sulphuraria, both phycobiliprotein types bind phycocyanobilin, despite lacking the canonical synthesizing gene PCYA. Instead, PEBA and PEBB are encoded, producing phycoerythrobilin, proposed to be later isomerized

Heat Shock Transcription Factor OsHsfc1a Enhances Rice Seedling Thermotolerance by Regulating OsMFT1 and Preserving Chloroplast Structure Under Heat Stress

Plant Biotechnology Journal, EarlyView.
ABSTRACT High‐temperature stress severely threatens rice (Oryza sativa L.) growth and productivity, particularly during the seedling stage, making heat tolerance an essential breeding target. In this study, we identified the heat shock transcription factor OsHsfc1a as a positive regulator of thermotolerance in rice seedlings.

Balancing chloroplast redox status – regulation of FNR binding and release [PDF]

, 2012
Working in synchrony, photosynthetic charge separation, electron transfer, and redox reactions generate proton motive force necessary for the synthesis of ATP and funneling of electrons toward stromal reducing equivalent NADPH.

Taxonomic and functional shifts in the microbiome of severely obese, prediabetic patients: Ketogenic diet versus energy‐matched standard diet

Diabetes, Obesity and Metabolism, Volume 28, Issue 3, Page 1826-1835, March 2026.
Abstract Aims Obesity and type 2 diabetes mellitus (T2DM) are among the leading global health challenges of the 21st century. While caloric restriction remains the cornerstone of weight loss interventions, ketogenic diets (KD), characterised by low carbohydrate and high fat intake, have been shown to improve metabolic health partly by modulating the ...

Ferredoxin:NADP(H) Oxidoreductase Abundance and Location Influences Redox Poise and Stress Tolerance [PDF]

, 2016
In linear photosynthetic electron transport, ferredoxin:NADP(H) oxidoreductase (FNR) transfers electrons from ferredoxin (Fd) to NADP(+). Both NADPH and reduced Fd (Fd(red)) are required for reductive assimilation and light/dark activation/deactivation ...
