Electroenzymatic CO2 Fixation

Angewandte Chemie International Edition, EarlyView.
Electroenzymatic CO2 fixation enables energy‐efficient, highly selective synthesis of complex molecules. Unlocking its full potential requires fundamental understanding of electrode‐coupled reductases and carboxylases. This review critically discusses available enzymes, product scope, and key thermodynamic and kinetic considerations, highlighting ...

Cuproptosis mediates copper-induced testicular spermatogenic cell death

Asian Journal of Andrology
Cuproptosis, a novel mechanism of programmed cell death, has not been fully explored in the context of spermatogenic cells. This study investigated the potential involvement of cuproptosis in spermatogenic cell death using a mouse model of copper ...

Light‐Driven Butyrate Production by a Probiotic Clostridium tyrobutyricum Enabled by a Cell‐Semiconductor Hybrid Interface

Food Chemistry International, EarlyView.
This schematic illustrates a light‐driven biohybrid system where CdS nanoparticles, mineralized on the probiotic Clostridium tyrobutyricum, inject photoelectrons to elevate intracellular NADH. This boosts the flux through key NADH‐dependent enzymes (GapA, Hbd, and Bcd), reprogramming metabolism to enhance butyrate yield by 33.2% and selectivity to 95.7%

Existence of specific binding sites in 1:1 oxidations of reduced parsley 2-Fe ferredoxin with inorganic complexes

Journal of the Chemical Society, Chemical Communications, 1978
Competition studies using redox active and inactive inorganic complexes have indicated that single unique binding sites are effective in individual reactions, and for the series of reactions investigated selection and utilization of different sites varies with the charge and/or ligand type on the complex.
