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 ...

Engineered toxin–intein antimicrobials can selectively target and kill antibiotic-resistant bacteria in mixed populations
(Springer Nature, 2019)
Targeted killing of pathogenic bacteria without harming beneficial members of host microbiota holds promise as a strategy to cure disease and limit both antimicrobial-related dysbiosis and development of antimicrobial ...

Compartmentalization, a key mechanism controlling the multi-tasking role of SnRK1 complex
(Oxford University Press, 2022)
SNF1-related protein kinase 1 (SnRK1), the plant ortholog of mammalian AMP-activated protein kinase/fungal (yeast) Sucrose Non-Fermenting 1 (AMPK/SNF1), plays a central role in metabolic responses to reduced energy levels ...

Signaling by hydrogen sulfide and cyanide through post-translational modification
(Oxford University Press, 2019)
Two cysteine metabolism-related molecules, hydrogen sulfide and hydrogen cyanide, which are considered toxic, have now been considered as signaling molecules. Hydrogen sulfide is produced in chloroplasts through the activity ...

Assessing the Epigenetic Status of Human Telomeres
(MDPI, 2019)
The epigenetic modifications of human telomeres play a relevant role in telomere functions and cell proliferation. Therefore, their study is becoming an issue of major interest. These epigenetic modifications are usually ...

Hydrogen sulfide signaling in plant adaptations to adverse conditions: molecular mechanisms
(Oxford University Press, 2021)
Hydrogen sulfide (H2S) is a signaling molecule that regulates critical processes and allows plants to adapt to adverse conditions. The molecular mechanism underlying H2S action relies on its chemical reactivity, and the ...

Exploring the Diversity of the Thioredoxin Systems in Cyanobacteria
(Multidisciplinary Digital Publishing Institute (MDPI), 2022)
Cyanobacteria evolved the ability to perform oxygenic photosynthesis using light energy to reduce CO2 from electrons extracted from water and form nutrients. These organisms also devel-oped light-dependent redox regulation ...

ZipN is an essential FtsZ membrane tether and contributes to the septal localization of SepJ in the flamentous cyanobacterium Anabaena
(Nature Publishing Group, 2019)
The organismic unit of heterocyst-forming cyanobacteria is a filament of communicating cells connected by septal junctions, proteinaceous structures bridging the cytoplasms of contiguous cells. This distinct bacterial ...

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 ...
