Revealing the structure of land plant photosystem II: the journey from negative‐stain EM to cryo‐EM

FEBS Letters, EarlyView.
Advances in cryo‐EM have revealed the detailed structure of Photosystem II, a key protein complex driving photosynthesis. This review traces the journey from early low‐resolution images to high‐resolution models, highlighting how these discoveries deepen our understanding of light harvesting and energy conversion in plants.

Spatiotemporal and quantitative analyses of phosphoinositides – fluorescent probe—and mass spectrometry‐based approaches

FEBS Letters, EarlyView.
Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

First Report on the Physicochemical and Sensory Characterization of Leucocarpa Olive Oil in Tunisia: A Comparative Study with Chemlali and Arbosana Olive Oils.

African and Mediterranean Agricultural Journal - Al Awamia
The conservation of rare olive cultivars is crucial for safeguarding agrobiodiversity and promoting the diversification of olive oil production. Leucocarpa, a white-fruited cultivar recently identified in Tunisia, remains poorly characterized despite its

SPECIFIC FEATURES OF NITROGEN METABOLISM DURING FERMENTATION OF MUST FROM WHITE GRAPE VARIETIES GROWN IN THE ODESSA REGION

Harčova Nauka ì Tehnologìâ, 2020
For wine quality management, nitrogen metabolism should be considered as a key process in the system “grape – wine.” Nitrogen is one of the dominant elements a grapevine receives from the soil.

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation

FEBS Letters, EarlyView.
Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

An upstream open reading frame regulates expression of the mitochondrial protein Slm35 and mitophagy flux

FEBS Letters, EarlyView.
This study reveals how the mitochondrial protein Slm35 is regulated in Saccharomyces cerevisiae. The authors identify stress‐responsive DNA elements and two upstream open reading frames (uORFs) in the 5′ untranslated region of SLM35. One uORF restricts translation, and its mutation increases Slm35 protein levels and mitophagy.

Facial cleansing wipes: A predictive model between consumer perception and in vitro lab measurements for rapid prototype screening

Journal of Industrial Textiles, 2022
Product development teams frequently develop many prototypes for screening before launching into the marketplace. Gaining customer feedback on each prototype is impossible because of constraints, such as tight timelines, budget, etc.

In situ molecular organization and heterogeneity of the Legionella Dot/Icm T4SS

FEBS Letters, EarlyView.
We present a nearly complete in situ model of the Legionella Dot/Icm type IV secretion system, revealing its central secretion channel and identifying new components. Using cryo‐electron tomography with AI‐based modeling, our work highlights the structure, variability, and mechanism of this complex nanomachine, advancing understanding of bacterial ...

The (Glg)ABCs of cyanobacteria: modelling of glycogen synthesis and functional divergence of glycogen synthases in Synechocystis sp. PCC 6803

FEBS Letters, EarlyView.
We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.
