Cadmium removal by Anabaena sp. ATCC 33047 immobilized in polyurethane foam
(Springer, 2015)
The nitrogen-fixing cyanobacterium Anabaena sp. ATCC 33047, which generates substantial amounts of exopolysaccharide, was immobilized by entrapment within the reticulate network of polyurethane foam discs. The immobilized ...

Dimerization model of the C-terminal RNA Recognition Motif of HuR
(wiley, 2015)
Human antigen R (HuR) is a ubiquitous 32kDa protein comprising three RNA Recognition Motifs (RRMs), whose main function is to bind Adenylate and uridylate Rich Elements (AREs) in 3′ UnTranslated Regions (UTRs) of mRNAs. ...

Site-directed Mutagenesis of Cytochromec 6 from Synechocystissp. PCC 6803
(Elsevier, 1999)
This paper reports the first site-directed mutagenesis analysis of any cytochrome c 6, a heme protein that performs the same function as the copper-protein plastocyanin in the electron transport chain of photosynthetic ...

Protein Dynamics Control of Electron Transfer in Photosynthetic Reaction Centers from Rps. Sulfoviridis
(American Chemical Society, 2008)
In the cycle of photosynthetic reaction centers, the initially oxidized special pair of bacteriochlorophyll molecules is subsequently reduced by an electron transferred over a chain of four hemes of the complex. Here, we ...

External loops at the ferredoxin-NADP+ reductase protein-partner binding cavity contribute to substrates allocation
(Elsevier, 2014)
Ferredoxin-NADP+ reductase (FNR) is the structural prototype of a family of FAD-containing reductases that catalyze electron transfer between low potential proteins and NAD(P)+/H, and that display a two-domain arrangement ...

Nitrogen-regulated antisense transcription in the adaptation to nitrogen deficiency in Nostoc sp. PCC 7120
(Oxford University Press, 2023-06-02)
Transcriptomic analyses using high-throughput methods have revealed abundant antisense transcription in bacteria. Antisense transcription is often due to the overlap of mRNAs with long 5′ or 3′ regions that extend beyond ...

HuR thermal stability is dependent on domain binding and upon phosphorylation
(Springer, 2012)
Human antigen R (HuR) is a multitasking RNA binding protein involved in posttranscriptional regulation by recognizing adenine- and uracile-rich elements placed at the 3′-untranslated regions of messenger RNAs (mRNAs). The ...

Photorespiration: regulation and new insights on the potential role of persulfidation
(Oxford University Press, 2023-07-24)
Photorespiration has been considered a 'futile' cycle in C3 plants, necessary to detoxify and recycle the metabolites generated by the oxygenating activity of Rubisco. However, several reports indicate that this metabolic ...

Starch synthase 4 is located in the thylakoid membrane and interacts with plastoglobule-associated proteins in Arabidopsis
(Wiley, 2014)
Starch synthesis requires the formation of a primer that can be subsequently elongated and branched. How this primer is produced, however, remains unknown. The control of the number of starch granules produced per chloroplast ...

The Efficient Functioning of Photosynthesis and Respiration in Synechocystis sp. PCC 6803 Strictly Requires the Presence of either Cytochrome c6 or Plastocyanin
(Elsevier, 2004)
In cyanobacteria, cytochrome c6 and plastocyanin are able to replace each other as redox carriers in the photosynthetic and respiratory electron transport chains with the synthesis of one or another protein being regulated ...
