PII, a homotrimeric very ancient and highly widespread (bacteria, archaea, plants) key sensor-transducer protein, conveys signals of abundance or poorness of carbon, energy and usable nitrogen, converting these signals into changes in the activities of ...

Evolutionary rewiring of bacterial regulatory networks
Bacteria have evolved complex regulatory networks that enable integration of multiple intracellular and extracellular signals to coordinate responses to environmental changes.

Cyanobacteria are the only oxygenic photosynthetic organisms that can fix nitrogen. In diazotrophic cyanobacteria, the regulation of photosynthesis during the diurnal cycle is hypothesized to be linked with nitrogen fixation and involve the D1 protein ...

Interactive regulation of nitrogen and aluminum in rice [PDF]
Despite many studies on the high aluminum (Al) tolerance of rice (Oryza sativa), its exact mechanisms remain largely unknown. It is also unclear why Al improves growth of some plants. Our research on interactions between nitrogen (N) and Al may help to understand these phenomena. Previously, we found that ammonium-supplemented rice was more Al tolerant

Genetics of Nitrogen Regulation in Methanococcus maripaludis [PDF]
Abstract We have used genetic methods in Methanococcus maripaludis to study nitrogen metabolism and its regulation. We present evidence for a “nitrogen regulon” in Methanococcus and Methanobacterium species containing genes of nitrogen metabolism that are regulated coordinately at the transcriptional level via a common repressor binding ...

Nitrogen regulation of arginase in Neurospora crassa [PDF]
The final products of the arginine catabolism that can be utilized as a nitrogen source in Neurospora crassa are ammonium, glutamic acid, and glutamine. The effect of these compounds on arginase induction by arginine was studied. In wild-type strain 74-A, induction by arginine was almost completely repressed by glutamic acid plus ammonium, whereas ...

Electricity network regulation in the EU : The challenges ahead for transmission and distribution
The UK model of incentive regulation of power grids was at one time the most advanced, and elements of it were adopted throughout the EU. This model worked well, particularly in the context of limited investment and innovation, a single and strong ...

Regulation of nitrogen fixation in Azospirillum brasilense [PDF]
The regulation of nitrogen fixation in Azospirillum brasilense is very complicated, and it responds to exogenous fixed nitrogen or a change of oxygen concentration. This regulation occurs at both transcriptional and posttranslational levels. Unlike regulation seen in Klebsiella pneumoniae, transcription of nifA does not require NTRB/NTRC in A ...
