The Computer-Assisted Sequence Annotation (CASA) workflow for enzyme discovery. [PDF]

Appl Plant Sci
Abstract Premise With the advent of inexpensive nucleic acid sequencing and automated annotation at the level of basic functionality, the central problem of enzyme discovery is no longer finding active sequences, it is determining which ones are suitable for further study.

Proton Relays in Molecular Catalysis for Hydrogen Evolution and Oxidation: Lessons From the Mimicry of Hydrogenases and Electrochemical Kinetic Analyses

Angewandte Chemie, Volume 136, Issue 52, December 20, 2024.
This review focuses on the role of proton relays at the active sites of hydrogenases, highlighting their significance in hydrogen evolution and oxidation. It then explores biomimetic and bioinspired systems containing such proton relays from the literature, discusses the electrochemical framework for enhancing catalysis, and identifies key parameters ...

Resilience of soil microbial activity and of amino acid dynamics to the removal of plant carbon inputs during winter Resiliência da atividade microbiana e da dinâmica de amino-ácidos na remoção das adições de carbono das plantas, durante o inverno

Scientia Agricola, 2009
Many temperate agricultural soils have prolonged periods in the winter when plant carbon inputs to the soil are low. Soil maintained at low temperature in the absence of plants was used to simulate the conditions in a vineyard soil during winter.

GABAergic Modulation and Neurobehavioral Effects of Arjunolic Acid, a Pentacyclic Triterpene Isolated From Combretum Mellifluum Eichler: In Vivo and Molecular Docking Evaluation

Chemistry &Biodiversity, Volume 23, Issue 3, March 2026.
ABSTRACT This study investigated the neuropharmacological effects of arjunolic acid, with a particular focus on its anxiolytic and anticonvulsant properties. To this end, in vivo tests were performed on adult zebrafish (Danio rerio) and in silico molecular docking analyses were conducted.

Enhanced CO2 Electroreduction Through Electrostatic Functionalization of Iron Porphyrin

ChemCatChem, Volume 18, Issue 3, 12 February 2026.
This study introduces an iron porphyrin catalyst for CO2 reduction, featuring an ortho‐positioned imidazolium group designed to probe electrostatic effects. The catalyst exhibits a 100‐fold increase in activity over its unsubstituted counterpart at similar potentials.
