A Phosphorylation‐Dependent Partner‐Switching‐Like Module Regulates a Glycosyltransferase Required for Heterocyst Polysaccharide Layer Formation in Anabaena sp. Strain PCC 7120

Molecular Microbiology, EarlyView.
The glycosyltransferase All4160 is regulated by the reversible phosphorylation of Ser74. The kinase Alr3423 phosphorylates and inactivates All4160, while the SpoIIE‐like phosphatase HenR restores its activity through dephosphorylation. A nonphosphorylatable variant of All4160 bypasses the need for HenR, which demonstrates that a phosphorylation ...

Iterative Genome Engineering Platform Enables Efficient Sucrose Biosynthesis From CO2 in Photosynthetic Synechococcus elongatus UTEX 2973

Plant Biotechnology Journal, EarlyView.
ABSTRACT The single crossover occurring via homologous recombination is a common phenomenon existing among microbes like Escherichia coli, Bacillus subtilis, Vibrio natriegens, Gluconobacter oxydans and most cyanobacteria species, threatening the stability of engineered strains and challenging iterative genetic engineering. Among them, we take the fast‐

Anaplerotic reactions in Anabaena cylindrica [PDF]

FEBS Letters, 1983
Anaplerotic reactions occur in heterocysts and vegetative cells of Anabaena cylindrica. This cyanobacterium possesses phosphoenolpyruvate carboxylase and malic enzyme, but no pyruvate carboxylase and isocitrate lyase. Heterocysts contain all the enzymes for the conversion of glucose 6‐phosphate to oxoglutarate and may not be dependent on a supply with ...

Phylogenomic Analysis of Secondary Metabolism in the Toxic Cyanobacterial Genera Anabaena, Dolichospermum and Aphanizomenon

Toxins, 2020
Cyanobacteria produce an array of toxins that pose serious health risks to humans and animals. The closely related diazotrophic genera, Anabaena, Dolichospermum and Aphanizomenon, frequently form poisonous blooms in lakes and brackish waters around the ...

Ecological niches and biogeography of nitrogen‐fixing plants in Europe

Plant Biology, EarlyView.
Despite sharing N fixation as a common trait, European legume and actinorhizal plant lineages occupy strikingly divergent ecological niches shaped by their evolutionary histories and physiological adaptations. Advanced symbiont control allows IRLC legumes to expand into northern, mesic regions, while non‐IRLC legumes are more common in Mediterranean ...

The Incorporation and Metabolism of Glucose by Anabaena variabilis [PDF]

Journal of General Microbiology, 1968
SUMMARY: The incorporation and metabolism of glucose by the blue-green alga Anabaena variabilis is described. Experiments with [14C]glucose indicated that this compound contributed up to 46 % of the total dry wt of organism. Respiratory studies with [I-14C] and [6-14C] showed that the pentose phosphate pathway was the major route of glucose ...

Cyanobacterial Mn-catalase ‘KatB’: Molecular link between salinity and oxidative stress resistance

Communicative & Integrative Biology, 2016
Catalases are ubiquitous enzymes that detoxify H2O2 in virtually all organisms exposed to oxygen. The filamentous, nitrogen-fixing cyanobacterium, Anabaena PCC 7120, shows the presence of 2 genes (katA and katB) that encode Mn-catalases. We have recently

Amino Acid Transporters and Release of Hydrophobic Amino Acids in the Heterocyst-Forming Cyanobacterium Anabaena sp. Strain PCC 7120

Life, 2015
Anabaena sp. strain PCC 7120 is a filamentous cyanobacterium that can use inorganic compounds such as nitrate or ammonium as nitrogen sources. In the absence of combined nitrogen, it can fix N2 in differentiated cells called heterocysts.

Photosynthesis regulation impacts carbon and nitrogen assimilation in the diazotrophic cyanobacterium Anabaena sp. PCC 7120

New Phytologist, Volume 251, Issue 1, Page 94-110, July 2026.
Model of intercellular functional coordination in Anabaena. Summary Diazotrophic cyanobacteria fix both atmospheric carbon (C) and nitrogen (N) into biomass, but the two assimilation pathways are not compatible. Species like Anabaena sp. PCC 7120 physically separate C and N assimilation in different cell types.

Dynamical magnetostructural properties of Anabaena ferredoxin [PDF]

Proceedings of the National Academy of Sciences, 2007
A mixed quantum/classical investigation of the dynamical magnetostructural properties, that is, “magnetodynamics,” of oxidized Anabaena PCC7119 ferredoxin is carried out at room temperature in two distinct conformational states.
