Great metalloclusters in enzymology [PDF]
, 2002 Metallocluster-containing enzymes catalyze some of the most basic redox transformations in the biosphere. The reactions catalyzed by these enzymes typically involve small molecules such as N2, CO, and H2 that are used to generate both chemical building ...

Investigating N2 Fixation Using a Bulky Fe(bisphosphine)2 Framework
Chemistry – A European Journal, Volume 32, Issue 1, 2 January 2026.The bulky Fe(0) N2 complex Fe(N2)(dibpe)2 has been prepared and efficiently produces NH3/N2H4 upon treatment with acid, similarly to previously investigated Fe(N2)(depe)2. However, it performs much less effectively during attempted catalytic N2 fixation, allowing investigation of the crucial role of steric hindrance in steps such as N2 binding and ...

Nodule Initiation Elicited by Noninfective Mutants of \u3cem\u3eRhizobium phaseoli\u3c/em\u3e [PDF]
, 1985 Rhizobium phaseoli CE106, CE110, and CE115, originally derived by transposon mutagenesis (Noel et al., J. Bacteriol. 158:149-155, 1984), induced the formation of uninfected root nodule-like swellings on bean (Phaseolus vulgaris).

Dinitrogen-Fixing Cyanobacteria in Microbial Mats of Two Shallow Coral Reef Ecosystems [PDF]
, 2009 Dinitrogen-fixing organisms in cyanobacterial mats were studied in two shallow coral reef ecosystems: La Reunion Island, southwestern Indian Ocean, Sesoko (Okinawa) Island, and northwestern Pacific Ocean.

Expanding the Alkene‐Forming Capability of the Pseudomonas Savastanoi Ethylene‐Forming Enzyme
ChemCatChem, Volume 18, Issue 1, 15 January 2026.Bump‐and‐hole studies on the Pseudomonas savastanoi ethylene‐forming enzyme (PsEFE) enable formation of low levels of alkene products other than ethylene from naturally occurring 2‐oxoglutarate derivatives. The results show that plants and/or microorganisms have potential for enzyme‐catalyzed production of propylene and 1‐butylene, potentially to exert

Limnology and Oceanography, Volume 71, Issue 1, January 2026.Abstract Heterotrophic diazotrophs are potentially important to the nitrogen cycle in freshwater ecosystems, yet their abundance, N2 fixation rates, diversity, and association with aggregates remain poorly understood. This study elucidates the contribution of freshwater heterotrophic diazotrophs as free‐living or aggregate‐associated cells to total N2 ...

The genetics of symbiotic nitrogen fixation: comparative genomics of 14 Rhizobia Strains by resolution of protein clusters. [PDF]
, 2017 The symbiotic relationship between legumes and nitrogen fixing bacteria is critical for agriculture, as it may have profound impacts on lowering costs for farmers, on land sustainability, on soil quality, and on mitigation of greenhouse gas emissions ...

Low-energy spectrum of iron-sulfur clusters directly from many-particle quantum mechanics [PDF]
, 2014 FeS clusters are a universal biological motif. They carry out electron transfer, redox chemistry, and even oxygen sensing, in diverse processes including nitrogen fixation, respiration, and photosynthesis. The low-lying electronic states are key to their
