Structure of transcription factor HetR required for heterocyst differentiation in cyanobacteria. [PDF]
Proc Natl Acad Sci U S A, 2011 HetR is an essential regulator of heterocyst development in cyanobacteria. HetR binds to a DNA palindrome upstream of the hetP gene. We report the crystal structure of HetR from Fischerella at 3.0 Å.

Life, 2022 The cyanobacterium Anabaena sp. PCC 7120 forms filaments of communicating cells. Under conditions of nitrogen scarcity, some cells differentiate into heterocysts, allowing the oxygen-sensitive N2-reduction system to be expressed and operated in oxic ...

Life, 2020 The filamentous cyanobacterium Anabaena sp. PCC 7120 produces, during the differentiation of heterocysts, a short peptide PatS and a protein HetN, both containing an RGSGR pentapeptide essential for activity.

Control of phycobiliprotein proteolysis and heterocyst differentiation in Anabaena [PDF]
Journal of Bacteriology, 1980 Phycobiliprotein degradation can be initiated in cultures of the cyanobacterium Anabaena by removal of combined nitrogen from the medium. Certain strains of Anabaena differentiate cells specialized for aerobic nitrogen fixation (heterocysts) under such conditions.

Cyt c6-3: A new isoform of photosynthetic Cyt c6 exclusive to heterocyst-forming cyanobacteria [PDF]
, 2017 All known cyanobacteria contain Cyt c6, a small soluble electron carrier protein whose main function is to transfer electrons from the Cyt b6 f complex to PSI, although it is also involved in respiration.

Differentiation in Nostoc muscorum: Nitrogenase Is Synthesized in Heterocysts [PDF]
Proceedings of the National Academy of Sciences, 1973 Cellular differentiation can be observed in certain filamentous blue-green algae after transfer of the cells from medium containing NH 4 + or NO 3 - to nitrogen-free medium.

HETEROCYST DIFFERENTIATION AND POLARITY IN CALOTHRIX [PDF]
New Phytologist, 1978 SUMMARYWhen grown in a nitrogen‐free medium Calothrix brevissima West has a basal heterocyst followed by a filament of cells of decreasing size. In a nitrate medium, the alga does not form heterocysts but partial polarity, i.e. tapering of the filaments, remains.

Frontiers in Microbiology, 2020 Hanks-type kinases encoding genes are present in most cyanobacterial genomes. Despite their widespread pattern of conservation, little is known so far about their role because their substrates and the conditions triggering their activation are poorly ...

Frontiers in Plant Science, 2020 The heterocysts present in filamentous cyanobacteria such as Anabaena sp. PCC 7120 are known to be regulated by HetN and PatS, the repressors of heterocyst differentiation; therefore, the inactivation of these proteins will result in the formation of ...
