Characterization of TrxC, an Atypical Thioredoxin Exclusively Present in Cyanobacteria
(MDPI, 2018)
Cyanobacteria form a diverse group of oxygenic photosynthetic prokaryotes considered to be the antecessor of plant chloroplast. They contain four different thioredoxins isoforms, three of them corresponding to m, x and y ...

You have access HCN regulates cellular processes through posttranslational modification of proteins by S-cyanylation
(American Society of Plant Biologists, 2019)
Hydrogen cyanide (HCN) is coproduced with ethylene in plant cells and is primarily enzymatically detoxified by the mitochondrial β-CYANOALANINE SYNTHASE (CAS-C1). Permanent or transient depletion of CAS-C1 activity in ...

FtsZ of filamentous, heterocyst-forming cyanobacteria has a conserved N-Terminal peptide required for normal FtsZ polymerization and cell division
(Frontiers Media, 2018-10-02)
Filamentous cyanobacteria grow by intercalary cell division, which should involve distinct steps compared to those producing separate daughter cells. The N-terminal region of FtsZ is highly conserved in the clade of ...

FraH is required for reorganization of intracellular membranes during heterocyst differentiation in Anabaena sp. strain PCC 7120
(American Society for Microbiology, 2011)
In the filamentous, heterocyst-forming cyanobacteria, two different cell types, the CO2-fixing vegetative cells and the N2-fixing heterocysts, exchange nutrients and regulators for diazotrophic growth. In the model organism ...

A combinatorial strategy of alternative promoter use during differentiation of a heterocystous cyanobacterium
(Wiley, 2017-06-06)
Heterocystous cyanobacteria such as Nostoc sp. are filamentous photosynthetic organisms that, in response to nitrogen deficiency, undergo a differentiation process transforming certain, semi-regularly spaced cells into ...

2-Cys Peroxiredoxins Participate in the Oxidation of Chloroplast Enzymes in the Dark
(Elsevier, 2018)
Most redox-regulated chloroplast enzymes are reduced during the day and oxidized during the night. While the reduction mechanism of light-dependent enzymes is well known, the mechanism mediating their oxidation in the dark ...

Hydrogen Sulfide Signaling in Plants: Emerging Roles of Protein Persulfidation
(Frontiers Media, 2018)
Hydrogen sulfide (H2S) has been largely referred as a toxic gas and environmental hazard, but recent years, it has emerged as an important gas-signaling molecule with effects on multiple physiological processes in both ...

Orientation of the central domains of KSRP and its implications for the interaction with the RNA targets
(Oxford University Press, 2010)
KSRP is a multi-domain RNA-binding protein that recruits the exosome-containing mRNA degradation complex to mRNAs coding for cellular proliferation and inflammatory response factors. The selectivity of this mRNA degradation ...

Determination of Arabidopsis thaliana telomere length by PCR
(Nature Publishing Group, 2014)
In humans, telomere length studies have acquired great relevance because the length of telomeres has been related to natural processes like disease, aging and cancer. However, very little is known about the influence of ...
