Specific mutations in the permease domain of septal protein SepJ differentially affect functions related to multicellularity in the filamentous cyanobacterium Anabaena
(Shared Science Publishers, 2018)
Filamentous, heterocyst-forming cyanobacteria are multicellular organisms in which growth requires the activity of two interdependent cell types that exchange nutrients and regulators. Vegetative cells provide heterocysts ...

The LysR-type transcription factor PacR is a global regulator of photosynthetic carbon assimilation in Anabaena
(Blackwell Publishing, 2015)
Cyanobacteria perform water-splitting photosynthesis and are important primary producers impacting the carbon and nitrogen cycles at global scale. They fix CO2 through ribulose-bisphosphate carboxylase/oxygenase (RuBisCo) ...

Two exopolyphosphatases with distinct molecular architectures and substrate specificities from the thermophilic green-sulfur bacterium Chlorobium tepidum TLS
(Microbiology Society, 2014)
The genome of the thermophilic green-sulfur bacterium Chlorobium tepidumTLS possesses two genes encoding putative exopolyphosphatases (PPX; EC 3.6.1.11), namely CT0099 (ppx1, 993 bp) and CT1713 (ppx2, 1557 bp). The predicted ...

The heterocyst differentiation transcriptional regulator HetR of the filamentous cyanobactrium Anabaena forms tetramers and can be regulated by phosphorylation
(Wiley, 2016)
Many filamentous cyanobacteria respond to the external cue of nitrogen scarcity by the differentiation of heterocysts, cells specialized in the fixation of atmospheric nitrogen in oxic environments. Heterocysts follow a ...

Predicting substrate exchange in marine diatom-heterocystous cyanobacteria symbioses
(Wiley, 2020)
In the open ocean, some phytoplankton establish symbiosis with cyanobacteria. Some partnerships involve diatoms as hosts and heterocystous cyanobacteria as symbionts. Heterocysts are specialized cells for nitrogen fixation, ...
