The Distinctive Regulation of Cyanobacterial Glutamine Synthetase
(MDPI AG, 2018-10-27)
Glutamine synthetase (GS) features prominently in bacterial nitrogen assimilation as it catalyzes the entry of bioavailable nitrogen in form of ammonium into cellular metabolism. The classic example, the comprehensively ...

Sub-cellular localization and complex formation by aminoacyl-tRNA synthetases in cyanobacteria: Evidence for interaction of membrane-anchored ValRS with ATP synthase
(Frontiers Media S.A., 2016)
tRNAs are charged with cognate amino acids by aminoacyl-tRNA synthetases (aaRSs) and subsequently delivered to the ribosome to be used as substrates for gene translation. Whether aminoacyl-tRNAs are channeled to the ribosome ...

RNase P RNA from the Recently Evolved Plastid of Paulinella and from Algae
(MDPI AG, 2014)
The RNase P RNA catalytic subunit (RPR) encoded in some plastids has been found to be functionally defective. The amoeba Paulinella chromatophora contains an organelle (chromatophore) that is derived from the recent ...

NsrR1, a Nitrogen stress-repressed sRNA, contributes to the regulation of nblA in Nostoc sp. PCC 7120
(Frontiers Media, 2018-09-24)
Small regulatory RNAs (sRNAs) are currently considered as major post-transcriptional regulators of gene expression in bacteria. The interplay between sRNAs and transcription factors leads to complex regulatory networks in ...

Diversity of N2-fixing cyanobacteria from Andalusian paddy fields and analysis of their potential as bioinoculants
(Universidad Pablo de Olavide, Sevilla, 2019)
The marshes of the Guadalquivir River contain the largest area of rice cultivation in Spain, where more than 40,000 ha are used every year for rice production. These wetland areas provide a perfect place for rice cultivation, ...

Identification of conserved and potentially regulatory small RNAs in heterocystous cyanobacteria
(Frontiers Media S.A., 2016)
Small RNAs (sRNAs) are a growing class of non-protein-coding transcripts that participate in the regulation of virtually every aspect of bacterial physiology. Heterocystous cyanobacteria are a group of photosynthetic ...

Overexpression of SepJ alters septal morphology and heterocyst pattern regulated by diffusible signals in Anabaena
(Wiley, 2016)
Filamentous, N2 -fixing, heterocyst-forming cyanobacteria grow as chains of cells that are connected by septal junctions. In the model organism Anabaena sp. strain PCC 7120, the septal protein SepJ is required for filament ...

Isolation of Ribosomal Particles from the Unicellular Cyanobacterium Synechocystis sp. PCC 6803
(Bio-Protocol, 2017)
Isolation of ribosomal particles is an essential step in the study of ribosomal components as well as in the analysis of trans-acting factors that interact with the ribosome to regulate protein synthesis and modulate the ...

Cytochrome c6 is the main respiratory and photosynthetic soluble electron donor in heterocysts of the cyanobacterium Anabaena sp. PCC 7120
(Elsevier, 2019)
Cytochrome c6 is a soluble electron carrier, present in all known cyanobacteria, that has been replaced by plastocyanin in plants. Despite their high structural differences, both proteins have been reported to be isofunctional ...
