[EN] The large family of polypeptide GalNAc-transferases (GalNAc-Ts) controls with precision how GalNAc O-glycans are added in the tandem repeat regions of mucins (e.g., MUC1). However, the structural features behind the ... -
Novel carboxylate-based glycolipids: TLR4 antagonism, MD-2 binding and self-assembly properties
Cochet, Florent; Facchini, Fabio A.; Zaffaroni, Lenny; Billod, Jean-Marc; Coelho, Helena; Holgado, Aurora; Braun, Harald; Beyaert, Rudi; Jerala, Roman; Jiménez Barbero, Jesús; Martin-Santamaria, Sonsoles; Peri, Francesco (Nature Publishing, 2019-01-29)
New monosaccharide-based lipid A analogues were rationally designed through MD-2 docking studies. A panel of compounds with two carboxylate groups as phosphates bioisosteres, was synthesized with the same glucosamine-bis-succinyl ... -
Structural Characterization of N-Linked Glycans in the Receptor Binding Domain of the SARS-CoV-2 Spike Protein and their Interactions with Human Lectins
Lenza, Maria Pia; Oyenarte Santamaría, Iker; Diercks, Tammo; Quintana García, Jon Imanol; Gimeno, Ana; Coelho, Helena; Diniz, Ana; Peccati, Francesca; Delgado, Sandra; Bosch, Alexandre; Valle, Mikel; Millet Aguilar-Galindo, Oscar; Abrescia, Nicola A.G.; Palazón, Asís; Marcelo, Filipa; Jiménez Oses, Gonzalo; Jiménez Barbero, Jesús; Ardá, Ana ; Ereño Orbea, June (Wiley, 2020-10)
The glycan structures of the receptor binding domain of the SARS-CoV2 spike glycoprotein expressed in human HEK293F cells have been studied by using NMR. The different possible interacting epitopes have been deeply analysed ... -
Structures of the Inhibitory Receptor Siglec-8 in Complex with a High-Affinity Sialoside Analogue and a Therapeutic Antibody
