Environmental Toxicology, EarlyView.ABSTRACT Cyanobacterial harmful algal blooms (cyanoHABs) threaten human, animal, and ecosystem health and safety through production of toxic secondary metabolites. Microcystis, a cosmopolitan bloom‐forming cyanobacterial genus, is well‐known for producing hepatotoxic microcystins (MCs), but it can produce many other bioactive cyanopeptides, such as ...

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 ...

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 ...

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

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.

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 ...

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 ...

EcoMat, Volume 8, Issue 9, September 2026.A 3D‐printed polypyrrole/reduced graphene oxide (PPy/rGO) lattice anode with high porosity enhances biophotovoltaic (BPV) power density and current density by coordinating biofilm adhesion, light penetration, and endogenous mediator diffusion. Optimized PPy electropolymerization maximizes photocurrent and cell–electrode affinity.

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.
