Conformational and Structural Characterization of Carbohydrates and their Interactions Studied by NMR
Carbohydrates, either free or as glycans conjugated with other biomolecules, participate in a plethora of essential biological processes. Their apparent simplicity in terms of chemical functionality hides an extraordinary diversity and structural complexity. Deeply deciphering at the atomic level their structures is essential to understand their biological function and activities, but it is still a challenging task in need of complem Read More

GAG Multivalent Systems to Interact with Langerin
Authors: Javier Rojo, Pedro M. Nieto and José L. de PazLangerin is a C-type Lectin expressed at the surface of Langerhans cells, which play a pivotal role protecting organisms against pathogen infections. To address this aim, Langerin presents at least two recognition sites, one Ca2+-dependent and another one independent, which are capable to recognize a variety of carbohydrate ligands. In contrast to other lectins, Langerin recognizes sulfated glycosaminoglycans (G Read More

Towards Consistency in Geometry Restraints for Carbohydrates in the Pyranose form: Modern Dictionary Generators Reviewed
Authors: Robbie P. Joosten, Robert A. Nicholls and Jon AgirreMacromolecular restrained refinement is nowadays the most used method for improving the agreement between an atomic structural model and experimental data. Restraint dictionaries, a key tool behind the success of the method, allow fine-tuning geometric properties such as distances and angles between atoms beyond simplistic expectations. Dictionary generators can provide restraint target estimates derived from differe Read More

Aromatic Interactions in Glycochemistry: From Molecular Recognition to Catalysis
Aromatic platforms are ubiquitous recognition motifs occurring in protein carbohydrate- binding domains (CBDs), RNA receptors and enzymes. They stabilize the glycoside/ receptor complexes by participating in stacking CH/π interactions with either the α- or β- face of the corresponding pyranose units. In addition, the role played by aromatic units in the stabilization of glycoside cationic transition states has started being r Read More

A Computational Perspective on Molecular Recognition by Galectins
Authors: Reyes Núñez-Franco, Francesca Peccati and Gonzalo Jiménez-OsésThis article presents an overview of recent computational studies dedicated to the analysis of binding between galectins and small-molecule ligands. We first present a summary of the most popular simulation techniques adopted for calculating binding poses and binding energies and then discuss relevant examples reported in the literature for the three main classes of galectins (dimeric, tandem, and chimera). We show th Read More

Recent Advances on Multivalent Carbon Nanoform-Based Glycoconjugates
Authors: Javier Ramos-Soriano, Mattia Ghirardello and M. C. GalanMultivalent carbohydrate-mediated interactions are key to many biological processes including disease mechanisms. In order to study these important glycan-mediated interactions at a molecular level, carbon nanoforms such as fullerenes, carbon nanotubes or graphene and their derivatives have been identified as promising biocompatible scaffolds that can mimic the multivalent presentation of biologically relevan Read More

Structure-based Design of Anti-cancer Vaccines: The Significance of Antigen Presentation to Boost the Immune Response
Immunotherapy, alone or in combination with other therapies, is widely used against cancer. Glycoprotein Mucin 1 (MUC1), which is overexpressed and aberrantly glycosylated in tumor cells, is one of the most promising candidates to engineer new cancer vaccines. In this context, the development of stable antigens that can elicit a robust immune response is mandatory. Here, we describe the design and in vivo biologic Read More

Sugar-Derived Amidines and Congeners: Structures, Glycosidase Inhibition and Applications
Authors: Yves Blériot, Nicolas Auberger and Jérôme DésiréGlycosidases, the enzymes responsible for the breakdown of glycoconjugates, including di-, oligo- and polysaccharides, are present across all kingdoms of life. The extreme chemical stability of the glycosidic bond combined with the catalytic rates achieved by glycosidases makes them among the most proficient of all enzymes. Given their multitude of roles in vivo, inhibition of these enzymes is highly attractive with pote Read More

Peptidoglycan Deacetylases in Bacterial Cell Wall Remodeling and Pathogenesis
More LessThe bacterial cell wall peptidoglycan (PG) is a dynamic structure that is constantly synthesized, re-modeled and degraded during bacterial division and growth. Postsynthetic modifications modulate the action of endogenous autolysis during PG lysis and remodeling for growth and sporulation, but also they are a mechanism used by pathogenic bacteria to evade the host innate immune system. Modifications of the glycan backb Read More
