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 ...

Aliments de finition du canard de Barbarie : effets de leurs teneurs en protéines brutes sur les performances et la qualité de carcasse

INRAE Productions Animales, 1988
On a comparé, chez le caneton de Barbarie mâle, les effets de régimes de finition (56-84 jours) présentant des teneurs différentes en protéines brutes (130 à 170 g/kg). Des performances satisfaisantes sont obtenues avec une concentration située entre 140

A novel and efficient approach to high-throughput production of HLA-E/peptide monomer for T-cell epitope screening

Scientific Reports, 2021
Over the past two decades, there has been a great interest in the study of HLA-E-restricted αβ T cells during bacterial and viral infections, including recently SARS-CoV-2 infection.

Structural instability impairs function of the UDP‐xylose synthase 1 Ile181Asn variant associated with short‐stature genetic syndrome in humans

FEBS Letters, EarlyView.
The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...

Structural basis for the activation of acid ceramidase

Nature Communications, 2018
Acid ceramidase (aCDase) hydrolyzes lysosomal membrane ceramide into sphingosine and its dysfunction leads to a variety of disease phenotypes. Here, the authors present structures of aCDase in its proenzyme and autocleaved forms, which provides insight ...

Protéines laitières et sarcopénie [PDF]

, 2015
Avec l’âge, une diminution progressive de la masse musculaire est observée (sarcopénie). Celle-ci a bien sûr des conséquences sur la mobilité et l’autonomie des personnes âgées mais génère également un état de fragilité vis-à-vis des agressions ...

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.

Regulation of the Peptidoglycan Polymerase Activity of PBP1b by Antagonist Actions of the Core Divisome Proteins FtsBLQ and FtsN

mBio, 2019
Peptidoglycan (PG) is an essential constituent of the bacterial cell wall. During cell division, PG synthesis localizes at midcell under the control of a multiprotein complex, the divisome, allowing the safe formation of two new cell poles and separation
