In agroecosystems, nitrogen is one of the major nutrients limiting plant growth. To meet the
increased nitrogen demand in agriculture, synthetic fertilizers have been used extensively in …

Abstract Iron-sulfur (Fe/S) proteins are present in virtually all living organisms and are
involved in numerous cellular processes such as respiration, photosynthesis, metabolic …

Nitrogenase harbors three distinct metal prosthetic groups that are required for its activity.
The simplest one is a [4Fe-4S] cluster located at the Fe protein nitrogenase component. The …

Nitrogenases are responsible for biological nitrogen fixation, a crucial step in the
biogeochemical nitrogen cycle. These enzymes utilize a two-component protein system and …

SUMMARY PAS domains are newly recognized signaling domains that are widely
distributed in proteins from members of the Archaea and Bacteria and from fungi, plants …

▪ Abstract Iron-sulfur [Fe-S] clusters are ubiquitous and evolutionary ancient prosthetic
groups that are required to sustain fundamental life processes. Owing to their remarkable …

Azospirillum represents the best characterized genus of plant growth-promoting
rhizobacteria. Other free-living diazotrophs repeatedly detected in association with plant …

Biological nitrogen fixation, the conversion of atmospheric N2 to a form utilizable by higher
organisms, is catalyzed by the enzyme nitrogenase. This enzyme is found in relatively few …

Several specific primers for the nifH gene were tested with different pure telluric N2-fixing
strains. A PolF/PolR primer set provided successful amplification of 19 representative N2 …
