Classifying the metal dependence of uncharacterized nitrogenases

Frontiers in Microbiology, 2013
Nitrogenase enzymes have evolved complex iron-sulfur (Fe-S) containing cofactors that most commonly contain molybdenum (MoFe, Nif) as a heterometal but also exist as vanadium (VFe, Vnf) and heterometal independent (Fe-only, Anf) forms.

Effect of bio‐fertilization and edapho‐climatic conditions on chickpea nodulation, grain yields, and seed protein in a Mediterranean context: a meta‐analysis approach

Journal of the Science of Food and Agriculture, EarlyView.
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 ...

Natural Variation of NAR5 Determines Nitrogenase Activity and the Yield in Soybean

Advanced Science
Symbiotic nitrogen fixation (SNF) serves as a vital process through which legumes acquire atmospheric nitrogen, directly influencing plant growth, yield, and soil fertility.

Accessory Proteins of the Nitrogenase Assembly, NifW, NifX/NafY, and NifZ, Are Essential for Diazotrophic Growth in the Nonheterocystous Cyanobacterium Leptolyngbya boryana

Frontiers in Microbiology, 2019
Since nitrogenase is extremely vulnerable to oxygen, aerobic or micro-aerobic nitrogen-fixing organisms need to create anaerobic microenvironments in the cells for diazotrophic growth, which would be one of the major barriers to express active ...

Ecosystem retrogression enhances cross‐domain microbial stability and increases the genetic potential for nutrient cycling

mLife, EarlyView.
Abstract Ecosystem retrogression drives nutrient depletion, reduced productivity, and profound reorganization of soil microbial communities. Using amplicon sequencing and genome‐resolved metagenomics, we examined how cross‐domain microbial networks and functional gene potential respond to long‐term phosphorus and nitrogen limitation along the well ...

Outer‐Sphere Tuning of Synthetic Iron–Sulfur Clusters Within Nanoscale Cage Frameworks

Small, EarlyView.
Noncovalent encapsulation of a synthetic iron–sulfur cluster within hydrophobic, naphthalenediimide (NDI)‐paneled cages is shown to lead to dramatic changes in the electronic structure and covalency of the Fe─S core. ABSTRACT As atomic‐scale archetypes for multi‐electron transfer, iron–sulfur clusters are compelling candidates for the design of redox ...

Benzimidazole Anthelmintic Compounds Albendazole and Fenbendazole Show Distinct Toxicity on the Nitrogen Fixing Bacterium Mesorhizobium loti and Its Symbiosis With Lotus japonicus

Environmental Toxicology, EarlyView.
ABSTRACT Veterinary medicines, which reach the soil mostly through the application of contaminated manures, can affect beneficial soil microorganisms, such as nitrogen‐fixing rhizobia bacteria, which engage in important symbiotic associations with plants.

A colorimetric method to measure in vitro nitrogenase functionality for engineering nitrogen fixation

Scientific Reports, 2022
Biological nitrogen fixation (BNF) is the reduction of N2 into NH3 in a group of prokaryotes by an extremely O2-sensitive protein complex called nitrogenase. Transfer of the BNF pathway directly into plants, rather than by association with microorganisms,

A Phosphorylation‐Dependent Partner‐Switching‐Like Module Regulates a Glycosyltransferase Required for Heterocyst Polysaccharide Layer Formation in Anabaena sp. Strain PCC 7120

Molecular Microbiology, EarlyView.
The glycosyltransferase All4160 is regulated by the reversible phosphorylation of Ser74. The kinase Alr3423 phosphorylates and inactivates All4160, while the SpoIIE‐like phosphatase HenR restores its activity through dephosphorylation. A nonphosphorylatable variant of All4160 bypasses the need for HenR, which demonstrates that a phosphorylation ...

Nitrogenase Activity and Amounts of Nitrogenase Proteins in a Frankia-Alnus incana Symbiosis Subjected to Darkness [PDF]

Plant Physiology, 1991
Effects of prolonged darkness on nitrogenase activity in vivo, nitrogenase activity in vitro, and the amounts of nitrogenase proteins were studied in symbiotic Frankia. Plants of Alnus incana (L.) Moench in symbiosis with a local source of Frankia were grown for 9 to 10 weeks in an 18/6 hour light/darkness cycle.
