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

Thioredoxin reductase from Bacillus cereus exhibits distinct reduction and NADPH‐binding properties

FEBS Open Bio, 2021
Low‐molecular‐weight (low Mr) thioredoxin reductases (TrxRs) are homodimeric NADPH‐dependent dithiol flavoenzymes that reduce thioredoxins (Trxs) or Trx‐like proteins involved in the activation networks of enzymes, such as the bacterial class Ib ...

Biochemical characterization of ferredoxin-NADP+ reductase interaction with flavodoxin in Pseudomonas putida [PDF]

BMB Reports, 2012
Flavodoxin (Fld) has been demonstrated to bind to ferredoxin-NADP+ reductase A (FprA) in Pseudomonas putida. Tworesidues (Phe256, Lys259) of FprA are likely to be important forinteracting with Fld based on homology modeling.

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.

Carboxydotrophic Acetogenesis in Alkaline Conditions Results in Transient Formate Production by the Halo‐Alkaliphilic Acetogen Haloacetibacter carboxydivorans Gen. Nov. sp. Nov

Environmental Microbiology Reports, Volume 18, Issue 1, February 2026.
This work presents the physiological exploration of the halo‐alkaliphilic, carboxydotrophic acetogen bacterium MD4. In contrast to well‐characterised neutrophilic and slightly acidophilic acetogenic carboxydotrophs, this work shows an important role for formate production, instead of ethanol, as a redox exhaust mechanism in alkaline conditions ...

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

FEBS Letters, Volume 600, Issue 2, Page 164-187, January 2026.
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.

SNRK3.15 Is a Crucial Component of the Sulfur Deprivation Response in Arabidopsis thaliana

Plant Direct, Volume 10, Issue 1, January 2026.
ABSTRACT Sulfate deprivation (–S) results in numerous metabolic and phenotypic alterations in plants. Kinases are often key players in transducing nutrient status signals to molecular components involved in metabolic and developmental program regulation, but despite the physiological importance of sulfur, to date, no signaling kinases have been ...

Gene Expression Patterns during Light and Dark Infection of Prochlorococcus by Cyanophage. [PDF]

PLoS ONE, 2016
Cyanophage infecting the marine cyanobacteria Prochlorococcus and Synechococcus require light and host photosystem activity for optimal reproduction. Many cyanophages encode multiple photosynthetic electron transport (PET) proteins, which are presumed to

Cross‐Feeding of Carbon and Nitrogen Between Aquificales and Thermus in Hot Springs

Environmental Microbiology, Volume 28, Issue 1, January 2026.
Pampinifervens and Thermus populations are co‐distributed in hot springs in Yellowstone and Iceland. Genome reconstruction suggests Pampinifervens Flu05 cross feeds Thermus organic carbon and nitrogen, a phenomenon that was verified via co‐culture studies.
