Role of Two Cell Wall Amidases in Septal Junction and Nanopore Formation in the Multicellular Cyanobacterium Anabaena sp. PCC 7120
(Frontiers Media, 2017)
Filamentous cyanobacteria have developed a strategy to perform incompatible processes in one filament by differentiating specialized cell types, N2-fixing heterocysts and CO2-fixing, photosynthetic, vegetative cells. ...

Interactions of PatA with the divisome during heterocyst differentiation in anabaena
(American Society for Microbiology, 2020)
The Anabaena organismic unit is a filament of communicating cells. Under conditions of nitrogen scarcity, some cells along the filament differentiate into heterocysts, which are specialized in the fixation of atmospheric ...

ALGAEFUN with MARACAS, microALGAE FUNctional enrichment tool for MicroAlgae RnA-seq and Chip-seq AnalysiS
(BMC, 2022)
Background Microalgae are emerging as promising sustainable sources for biofuels, biostimulants in agriculture, soil bioremediation, feed and human nutrients. Nonetheless, the molecular mechanisms underpinning microalgae ...

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 ...

The restriction endonuclease Tru9I is a useful tool to analyze telomere sequences separately from interstitial telomeric sequences in Arabidopsis thaliana
(Scientific Research Publishing, 2012)
We have previously described a simple method to analyze the chromatin structure of Arabidopsis te- lomeres independently of that of Interstitial Telome- ric Sequences (ITSs). By using this method, we found that, whereas ...

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) ...

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 ...

NTRC Plays a Crucial Role in Starch Metabolism, Redox Balance, and Tomato Fruit Growth
(American Society of Plant Biologists, 2019)
NADPH-thioredoxin reductase C (NTRC) forms a separate thiol-reduction cascade in plastids, combining both NADPHthioredoxin reductase and thioredoxin activities on a single polypeptide. While NTRC is an important regulator ...

Electron Transfer Pathways and Dynamics of Chloroplast NADPH-dependent Thioredoxin Reductase C (NTRC)
(American Society for Biochemistry and Molecular Biology, 2012)
NADPH-dependent thioredoxin reductases (NTRs) contain a flavin cofactor and a disulfide as redox-active groups. The catalytic mechanism of standard NTR involves a large conformational change between two configurations. ...
