New insights into the evolutionary history of biological nitrogen fixation
Nitrogenase, which catalyzes the ATP-dependent reduction of dinitrogen (N2) to ammonia (NH3), accounts for roughly half of the bioavailable nitrogen supporting extant life. The fundamental requirement for fixed forms of nitrogen for life on Earth, both at present and in the past, has led to broad and significant interest in the origin and evolution of biological N2 fixation. One key question is...
متن کاملNew Perspectives in Biological Nitrogen Fixation Research
Nitrogen fixation, along with photosynthesis is the basis of all life on Earth. Current understanding suggests that no plant fixes its own nitrogen. Some plants (mainly legumes) fix nitrogen via symbiotic anaerobic microorganisms (mainly rhizobia). The nature of biological nitrogen fixation is that the dinitrogenase catalyzes the reaction splitting triple bond inert atmospheric nitrogen (N2) in...
متن کاملMechanistic insights into nitrogen fixation by nitrogenase enzymes.
Biological nitrogen fixation by nitrogenase enzymes is a process that activates dinitrogen (N2) one of the most inert molecules in nature, within the confines of a living organism and at ambient conditions. Despite decades of study, there are still no complete explanations as to how this is possible. Here we describe a model of N2 reduction using the Mo-containing nitrogenase (FeMoco) that can ...
متن کاملInsights into symbiotic nitrogen fixation in Medicago truncatula.
In silico analysis of the Medicago truncatula gene index release 8.0 at The Institute for Genomic Research identified approximately 530 tentative consensus sequences (TC) clustered from 2,700 expressed sequence tags (EST) derived solely from Sinorhizobium meliloti-inoculated root and nodule tissues. A great majority (76%) of these TC were derived exclusively from nitrogen-fixing and senescent n...
متن کاملFixating on metals: new insights into the role of metals in nodulation and symbiotic nitrogen fixation
Symbiotic nitrogen fixation is one of the most promising and immediate alternatives to the overuse of polluting nitrogen fertilizers for improving plant nutrition. At the core of this process are a number of metalloproteins that catalyze and provide energy for the conversion of atmospheric nitrogen to ammonia, eliminate free radicals produced by this process, and create the microaerobic conditi...
