Bacterial Pigments as Potential Antitumor Agents Against Gastrointestinal Cancers: A Comprehensive Systematic Review

open access: yesBiotechnology and Applied Biochemistry, EarlyView.
ABSTRACT Gastrointestinal cancers (GICs) constitute one of the leading causes of cancer‐related morbidity and mortality worldwide. Despite currently available therapeutic strategies, new approaches and procedures are needed for their prevention and treatment.

Degradation of PsbO by the Deg protease HhoA Is thioredoxin dependent. [PDF]

open access: yesPLoS ONE, 2012
The widely distributed members of the Deg/HtrA protease family play an important role in the proteolysis of misfolded and damaged proteins. Here we show that the Deg protease rHhoA is able to degrade PsbO, the extrinsic protein of the Photosystem II ...

Over‐Expression of a Phycocyanin‐Interferon Fusion and Differential Cleaving Efficiency in Cyanobacteria (Synechocystis sp. PCC 6803)

open access: yesBiotechnology and Bioengineering, EarlyView.
ABSTRACT Recombinant protein expression in heterologous biological systems is an expanding field in synthetic biology. Photosynthetic organisms have the potential to provide an efficient low‐cost platform for recombinant protein production because they require minimal growth nutrients and are less susceptible to zoonotic and other contaminants ...

Introducing an Arabidopsis thaliana Thylakoid Thiol/Disulfide-Modulating Protein Into Synechocystis Increases the Efficiency of Photosystem II Photochemistry

open access: yesFrontiers in Plant Science, 2019
Photosynthetic species are subjected to a variety of environmental stresses, including suboptimal irradiance. In oxygenic photosynthetic organisms, a major effect of high light exposure is damage to the Photosystem II (PSII) reaction-center protein D1 ...

Heterologous plastoquinone production using a newly identified O2‐dependent cyanobacterial hydroxylase

open access: yesThe FEBS Journal, EarlyView.
In this study, we confirm that PlqH is the hydroxylase operating in plastoquinone biosynthesis in photosynthetic cyanobacteria (Cyanobacteriia). Our phylogenetic analyses demonstrate that cyanobacterial PlqH homologues originated from hydroxylases involved in ubiquinone biosynthesis in bacteria. Plastoquinone production in Escherichia coli was achieved

Glycogen synthase isoforms in Synechocystis sp. PCC6803: identification of different roles to produce glycogen by targeted mutagenesis. [PDF]

open access: yesPLoS ONE, 2014
Synechocystis sp. PCC6803 belongs to cyanobacteria which carry out photosynthesis and has recently become of interest due to the evolutionary link between bacteria and plant species.

Reciprocal Effect of Copper and Iron Regulation on the Proteome of Synechocystis sp. PCC 6803

open access: yesFrontiers in Bioengineering and Biotechnology, 2021
Cyanobacteria can acclimate to changing copper and iron concentrations in the environment via metal homeostasis, but a general mechanism for interpreting their dynamic relationships is sparse.

Phycocyanobilin biosynthesis in Galdieria sulphuraria requires isomerization of phycoerythrobilin synthesized by bilin reductases

open access: yesThe FEBS Journal, EarlyView.
The biosynthesis of bilins, tetrapyrroles essential for light harvesting and sensing, is performed by specific enzymes (FDBRs). In Galdieria sulphuraria, both phycobiliprotein types bind phycocyanobilin, despite lacking the canonical synthesizing gene PCYA. Instead, PEBA and PEBB are encoded, producing phycoerythrobilin, proposed to be later isomerized

The C Terminus of the Ribosomal-Associated Protein LrtA Is an Intrinsically Disordered Oligomer [PDF]

open access: yes, 2018
The 191-residue-long LrtA protein of Synechocystis sp. PCC 6803 is involved in post-stress survival and in stabilizing 70S ribosomal particles. It belongs to the hibernating promoting factor (HPF) family, intervening in protein synthesis.

Cyt c6-3: A new isoform of photosynthetic Cyt c6 exclusive to heterocyst-forming cyanobacteria [PDF]

open access: yes, 2017
All known cyanobacteria contain Cyt c6, a small soluble electron carrier protein whose main function is to transfer electrons from the Cyt b6 f complex to PSI, although it is also involved in respiration.
