Energy Transduction in Nitrogenase [PDF]
Nitrogenase is a complicated two-component enzyme system that uses ATP binding and hydrolysis energy to achieve one of the most difficult chemical reactions in nature, the reduction of N2 to NH3. One component of the Mo-based nitrogenase system, Fe protein, delivers electrons one at a time to the second component, the catalytic MoFe protein.

Sulfur‐Rich μ‐O Diiron Catalyst for Electrochemical Hydrogen Production
A diferric μ‐oxido complex supported by a sulfur‐rich scaffold acts as a proton‐reduction electrocatalyst for H2 production via a μ‐hydroxido species. An aminodithiophenolate scaffold with an NS2 donor set supports diiron complex formation. The diferrous precursor activates O2, giving rise to a diferric μ‐oxido species, which acts as a proton‐reduction

Diversity and Functional Analysis of the FeMo-Cofactor Maturase NifB
One of the main hurdles to engineer nitrogenase in a non-diazotrophic host is achieving NifB activity. NifB is an extremely unstable and oxygen sensitive protein that catalyzes a low-potential SAM-radical dependent reaction.

Effect of Thiols for Nitrogen Reduction to Ammonia [PDF]
Ammonia is an important chemical used for fertilizers and also a potential carbon-free hydrogen storage medium. The Haber-Bosch process is the main production process, which requires large energy- and capital-input. Therefore, it is crucial to develop an

Abstract Chickpeas (Cicer arietinum L.) serve as a protein‐rich staple, particularly in Mediterranean countries, where they are often grown in marginal and water‐stressed areas. This meta‐analysis synthesized evidence from peer‐reviewed publications across Mediterranean countries to assess how chickpea rhizobial inoculation influences chickpea ...

Complete Genomes of Symbiotic Cyanobacteria Clarify the Evolution of Vanadium-Nitrogenase. [PDF]
Plant endosymbiosis with nitrogen-fixing cyanobacteria has independently evolved in diverse plant lineages, offering a unique window to study the evolution and genetics of plant-microbe interaction.

Feedback inhibition of nitrogenase [PDF]
No inhibition of nitrogenase activity by physiological levels of NH4+ or carbamyl phosphate was observed in extracts of Azotobacter vinelandii. All of the 15N2 reduced by cultures which received no NH4+ was found in the cells. By contrast, more than 95% of the 15N2 reduced by cultures which had been given NH4+ was found in the medium.

Agroforestry and enhanced rock weathering: A dual strategy for sustainable cacao
Cacao production is both economically vital and environmentally intensive, presenting a major sustainability challenge as a crop largely cultivated by smallholder farmers in climate‐vulnerable regions. This review synthesises evidence that integrating agroforestry with enhanced rock weathering (EW) may significantly reduce emissions from cacao ...
