The ability of P II to sense important metabolites and integrate signals deriving from energy status (ATP and ADP ratio), carbon (2-oxogluratate) and nitrogen (glutamine and 2-oxoglutarate) levels were capitalized during evolution such that P II can act as a dissociable regulatory subunit of a range of transporters, transcriptional regulators ...

Azotobacter can fix at least 10 μg of nitrogen per gram of glucose consumed. Nitrogen fixation requires molybdenum ions, but they can be partially or completely replaced by vanadium ions. If atmospheric nitrogen is not fixed, the source of nitrogen can alternatively be nitrates, ammonium ions, or amino acids.
A nitrogen fixation package is a piece of research equipment for studying nitrogen fixation in plants. One product of this kind, the Q-Box NF1LP made by Qubit Systems, operates by measuring the hydrogen (H 2 ) given off in the nitrogen-fixing chemical reaction enabled by nitrogenase enzymes.
Aspergillus fumigatus can survive on a variety of different nitrogen sources, and the assimilation of nitrogen is of clinical importance, as it has been shown to affect virulence. [ 25 ] [ 30 ] Proteins involved in nitrogen assimilation are transcriptionally regulated by the AfareA gene in A. fumigatus .
