NtcA, highly conserved in cyanobacteria, regulates the expression of a large number of genes involved in nitrogen and carbon metabolisms, photosynthesis, and stress responses. In the filamentous diazotrophic cyanobacterium Anabaena PCC 7120, NtcA is

Summary2-Oxoglutaric acid (2-OG), a Krebs cycle intermediate, is a signaling molecule in many organisms. To determine which form of 2-OG, the ketone or the ketal form, is responsible for its signaling function, we have synthesized and characterized v

In response to combined nitrogen starvation in the growth medium, the filamentous cyanobacterium Anabaena sp. PCC 7120 is able to develop a particular cell type, called a heterocyst, specialized in molecular nitrogen fixation. Heterocysts are regular

The amino acid sequence of the signal transducer P(II) (GlnB) of the oceanic photosynthetic prokaryote Prochlorococcus marinus strain PCC 9511 displays a typical cyanobacterial signature and is phylogenetically related to all known cyanobacterial gln

In the unicellular cyanobacteria that do not fix molecular nitrogen, interactions between N assimilation and C metabolism occur through the signal transducer PII and the global nitrogen regulator NtcA. Under high CO2 concentration, PII liganded to AT

Synechocystis PCC6803 displays two inorganic carbon-uptake processes, a low-affinity one (apparent Km: 300-400 microM) functional in cells grown under standard or limiting inorganic carbon concentrations, and one with a higher affinity (60 +/- 12 mic

patA expression is induced 3 to 6 h after nitrogen step-down. We establish that the transcription of patA is under the positive control of NtcA. The patA promoter region shows two conserved NtcA-binding boxes. These NtcA-binding sites and their inter

Heterocyst differentiation in filamentous cyanobacteria provides an excellent prokaryotic model for studying multicellular behaviour and pattern formation. In Anabaena sp. strain PCC 7120, for example, 5-10% of the cells along each filament are induc

In the heterocystous cyanobacterium Anabaena PCC 7120, the modification state of the signalling PII protein is regulated according to the nitrogen regime of the cells, as already observed in some unicellular cyanobacteria. However, during the adaptat
