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.

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 ...

Cytochrome c 6-like protein as a putative donor of electrons to photosystem I in the cyanobacterium Nostoc sp. PCC 7119 [PDF]

, 2011
Most organisms performing oxygenic photosynthesis contain either cytochrome c 6 or plastocyanin, or both, to transfer electrons from cytochrome b 6-f to photosystem I. Even though plastocyanin has superseded cytochrome c 6 along evolution, plants contain

Dominance and toxicity without lethality: Exploring biomass, cyanometabolites, and Daphnia responses across Cyanobacterial strains

Journal of Phycology, EarlyView.
Abstract Cyanobacteria are cosmopolitan, important components of biomass with a remarkable ability to synthesize a diverse array of bioactive compounds, some of which may have toxic effects on other organisms and ecosystems. In this study, filamentous cyanobacterial strains isolated predominantly from temperate European freshwaters (Aphanizomenon ...

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

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 ...

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

New Phytologist, EarlyView.
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.

Low-dose alum application trialled as a management tool for internal nutrient loads in Lake Okaro, New Zealand [PDF]

, 2008
Aluminium sulfate (alum) was applied to Lake Okaro, a eutrophic New Zealand lake with recurrent cyanobacterial blooms, to evaluate its suitability for reducing trophic status and bloom frequency.

Long‐Term Safety and Efficacy of Pegvaliase in Japanese Adults With Phenylketonuria: Final Results of a Phase III Trial

JIMD Reports, Volume 67, Issue 3, May 2026.
ABSTRACT Phenylketonuria (PKU) is an inborn error of metabolism leading to phenylalanine (Phe) accumulation and consequent neurological, neurocognitive, and psychiatric symptoms. Pegvaliase, a pegylated recombinant phenylalanine ammonia lyase that metabolizes Phe, effectively reduced blood Phe in phase III studies in the United States. This multicenter,

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.
