NADPH Thioredoxin Reductase C and Thioredoxins Act Concertedly in Seedling Development
(American Society of Plant Biologists, 2017)
Thiol-dependent redox regulation of enzyme activity plays a central role in the rapid acclimation of chloroplast metabolism to ever-fluctuating light availability. This regulatory mechanism relies on ferredoxin reduced ...

Temperature-driven changeover in the electron-transfer mechanism of a thermophilic plastocyanin
(American Chemical Society, 2014)
Electron-transfer kinetics of the thermophilic protein Plastocyanin fromPhormidium laminosumadsorbed on 1,ω-alkanedithiol self-assembled monolayers (SAMs)deposited on gold have been investigated. The standard electron-transfer ...

Transcriptomic and Metabolomic Response to High Light in the Charophyte Alga Klebsormidium nitens
(Frontiers Media, 2022)
The characterization of the molecular mechanisms, such as high light irradiance resistance, that allowed plant terrestralization is a cornerstone in evolutionary studies since the conquest of land by plants played a pivotal ...

Conditional Expression of RNase P in the CyanobacteriumSynechocystis sp. PCC6803 Allows Detection of Precursor RNAs
(Elsevier, 2001)
We have constructed a strain (CT1) that expresses RNase P conditionally with the aim to analyze the in vivotRNA processing pathway and the biological role that RNase P plays inSynechocystis 6803. In this strain, the rnpBgene, ...

Inositol polyphosphates and TOR kinase signaling govern photosystem II protein phosphorylation and photosynthetic function under light stress in Chlamydomonas
(Wiley-Blackwell, 2021)
Stress and nutrient availability influence cell proliferation through complex intracellular signalling networks. In a previous study it was found that pyro-inositol polyphosphates (InsP7 and InsP8) produced by VIP1 kinase, ...

Chloroplast damage induced by the inhibition of fatty acid synthesis triggers autophagy in chlamydomonas
(American Society of Plant Biologists, 2018)
Fatty acids are synthesized in the stroma of plant and algal chloroplasts by the fatty acid synthase complex. Newly synthesized fatty acids are then used to generate plastidial lipids that are essential for chloroplast ...

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 ...

Antimalarial activity of cupredoxins: the interaction of Plasmodium Merozoite Surface Protein 119 (MSP119) and Rusticyanin
(American Society for Biochemistry and Molecular Biology, 2013)
Background: The interaction of MSP119 with the cupredoxin azurin inhibits the growth of Plasmodium falciparum in red blood cells. Results: Rusticyanin forms a well-defined complex with MSP119 upon binding at the same surface ...

New challenges in microalgae biotechnology
(Elsevier, 2016)
Photosynthetic protists, also called microalgae, have been systematically studied for more than a century. However, only recently broad biotechnological applications have fostered a novel wave of research on their ...

Molecular basis of FIR-mediated c-myc transcriptional control
(Nature Research, 2010)
The far upstream element (FUSE) regulatory system promotes a peak in the concentration of c-Myc during cell cycle. First, the FBP transcriptional activator binds to the FUSE DNA element upstream of the c-myc promoter. Then, ...
