CfrA, a novel carbon flow regulator, adapts carbon metabolism to nitrogen deficiency in cyanobacteria
(American Society of Plant Biologists, 2020)
Cyanobacteria unable to fix atmospheric nitrogen have evolved sophisticated adaptations to survive to long periods of nitrogen starvation. These genetic programs are still largely unknown—as evidenced by the many proteins ...

Redox control of copper homeostasis in cyanobacteria
(Taylor & Francis, 2012)
Copper is essential for all living organisms but is toxic when present in excess. Therefore organisms have developed homeostatic mechanism to tightly regulate its cellular concentration. In a recent study we have shown ...

A new member of the thioredoxin reductase family from early uxygenic photosynthetic organisms
(Oxford University Press, 2017)
Thioredoxins (Trxs) are key components of the redox system that regulates the activity of a spectrum of target proteins through dithiol-disulfide exchange reactions. Trxs are reduced by members of the Trx reductase (TR) ...

A loop unique to ferredoxin-dependent glutamate synthases is not absolutely essential for ferredoxin-dependent catalytic activity
(Springer, 2015)
It had been proposed that a loop, typically containing 26 or 27 amino acids, which is only present in monomeric, ferredoxin-dependent, “plant-type” glutamate synthases and is absent from the catalytic α-subunits of both ...

Proteomic pattern alterations of the cyanobacterium Synechocystis sp. PCC 6803 in response to cadmium, nickel and cobalt
(Elsevier, 2014)
Cyanobacteria represent the largest and most diverse group of prokaryotes capable of performing oxygenic photosynthesis and are frequently found in environments contaminated with heavy metals. Several studies have been ...

Stress response requires an efficient connection between glycogen and central carbon metabolism by phosphoglucomutases in cyanobacteria
(Oxford University Press, 2023-03-13)
Glycogen and starch are the main storage polysaccharides, acting as a source of carbon and energy when necessary. Interconversion of glucose-1-phosphate and glucose-6-phosphate by phosphoglucomutases connects the metabolism ...

The cyanobacterial ribosomal-associated protein LrtA from Synechocystis sp. PCC 6803 is an oligomeric protein in solution with chameleonic sequence properties
(MDPI, 2018)
The LrtA protein of Synechocystis sp. PCC 6803 intervenes in cyanobacterial post-stress survival and in stabilizing 70S ribosomal particles. It belongs to the hibernating promoting factor (HPF) family of proteins, involved ...

Redox regulation of glycogen biosynthesis in the cyanobacterium synechocystis sp. PCC 6803: Analysis of the AGP and glycogen synthases
(Oxford University Press, 2014)
Glycogen constitutes the major carbon storage source in cyanobacteria, as starch in algae and higher plants. Glycogen and starch synthesis is linked to active photosynthesis and both of them are degraded to glucose in the ...

Exploring the Diversity of the Thioredoxin Systems in Cyanobacteria
(Multidisciplinary Digital Publishing Institute (MDPI), 2022)
Cyanobacteria evolved the ability to perform oxygenic photosynthesis using light energy to reduce CO2 from electrons extracted from water and form nutrients. These organisms also devel-oped light-dependent redox regulation ...
