Structural features of halophilicity derived from the crystal structure of dihydrofolate reductase from the Dead Sea halophilic archaeon, Haloferax volcanii [PDF]
, 1982 Background: The proteins of halophilic archaea require high salt concentrations both for stability and for activity, whereas they denature at low ionic strength. The structural basis for this phenomenon is not yet well understood.

ChemCatChem, Volume 18, Issue 7, 14 April 2026.This review maps how electroenzymatic cascades that couple nitrogen‐cycle enzymes with C─N bond forming auxilary enzymes, powered by direct electron transfer (DET) or mediated electron transfer (MET), can upgrade N2 and waste nitrogen streams into value‐added amines, amides, amino acids, and other nitrogen‐based chemicals.

Food Science &Nutrition, Volume 14, Issue 4, April 2026.This study revealed that rumen microbiota significantly influence IMF deposition in Pingliang Red cattle through taxonomic and functional mechanisms. Limosilactobacillus panis and Fibrobacter succinogenes were identified as potential biomarkers for high IMF content.

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

Open questions in ferredoxin‐NADP+ reductase catalytic mechanism [PDF]
European Journal of Biochemistry, 2003 Ferredoxin (flavodoxin)‐NADP(H) reductases (FNR) are ubiquitous flavoenzymes that deliver NADPH or low potential one‐electron donors (ferredoxin, flavodoxin) to redox‐based metabolisms in plastids, mitochondria and bacteria. The plant‐type reductase is also the basic prototype for one of the major families of flavin‐containing electron transferases ...
