Room‐temperature crystal structure of a metal‐dependent W‐formate dehydrogenase by serial synchrotron crystallography

open access: yesActa Crystallographica Section D, Volume 82, Issue 9, Page 1072-1081, September 2026.
We report a room‐temperature serial synchrotron X‐ray crystallographic structural analysis of Nitratidesulfovibrio vulgaris formate dehydrogenase AB, an enzyme that reduces CO2 to formate.Metal‐dependent formate dehydrogenases (Fdhs) are a promising research target in efforts to mitigate climate change by developing active, efficient, selective and ...

Zinc addition and mowing alter the timing and duration of reproductive phenology in dominant plants of a meadow steppe

open access: yesFunctional Ecology, Volume 40, Issue 9, Page 2876-2888, September 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Plant phenology, while genetically determined, is highly responsive to environmental drivers such as soil nutrient availability and disturbance. As an essential micronutrient, zinc (Zn) plays a critical role in plant development by regulating key processes including RNA

Tyrosine residues at the substrate binding site in human NQO1 homodimer: Protein conformational dynamics and optimization of substrate binding geometry

open access: yesThe FEBS Journal, Volume 293, Issue 17, Page 5255-5281, September 2026.
Human NAD(P)H:quinone oxidoreductase 1 is a homodimeric flavoenzyme crucial for redox metabolism and linked to significant health issues. Point mutations at Tyr126 and Tyr128 demonstrate their essential roles in optimizing substrate binding geometry for catalysis, as well as in half‐site reactivity and conformational dynamics during the enzyme's ...

Hierarchical Nanostructured Photocatalysts for CO2 Photoreduction [PDF]

open access: yesCatalysts, 2019
Practical implementation of CO2 photoreduction technologies requires low-cost, highly efficient, and robust photocatalysts. High surface area photocatalysts are notable in that they offer abundant active sites and enhanced light harvesting.

Photoreduction of acetylene by heterocysts

Planta, 1971
Heterocysts of aerobically grown Anabaena cylindrica can reduce acetylene in the light, without added cofactors, up to 30% as rapidly as can the intact filaments from which they are derived.

Photoreduction of cycloalkanecarbaldehydes

Journal of the Chemical Society, Perkin Transactions 2, 1976
The photochemistry of cyclopropane- and cyclobutane-carbaldehyde in propan-2-ol with λ 300 nm has been studied. The primary chemical process upon irradiation of each of the two aldehydes in propan-2-ol is abstraction of the solvent methine hydrogen by both the 1S and 1T excited states of cyclopropanecarbaldehyde and only the 1T excited state of ...

PHOTOREDUCTION BY CHLAMYDOMONAS

American Journal of Botany, 1954
termed "photoreduction" by Gaffron (1940), who has studied this process in some detail particularly in Scenedesmus (Gaffron, 1945). This process has been shown to occur also in a number of other species of green, blue-green, and red algae (Frenkel and Rieger, 1951).
