Structural studies of SARS-CoV-2 spike protein domains bound to engineered glycan receptors and ACE2 fragments

FY 2020-21 · 2021-03-03

Summary
SARS-CoV-2 spike protein plays a critical role in initiating the infection process. There is evidence that in addition to the recognition of its receptor binding domain (RBD) by human ACE2 receptor, interactions of the N-terminal domain (NTD) with the sialic acid-based glycan receptors lining the respiratory tract are important to trigger its binding to ACE2, but structural determinants of this recognition remain elusive. As the atomic details of these interactions could be exploited to design and optimize therapeutic candidates, the Recipient will determine a series of crystal structures of spike domains complexed with various ACE2-derived peptides and glycan carbohydrates. Structural data generated will provide a solid basis for further engineering of both peptides and glycans with incremental improvements of binding and neutralization properties to the SARS-CoV-2 spike protein, paving the way for development of therapeutic candidates that can address not only the current pandemic but also future challenges.

Description (French)
La protéine de spicule du SRAS-CoV-2 joue un rôle essentiel dans le déclenchement du processus d’infection. Il est établi qu’outre la reconnaissance de son domaine de liaison au récepteur par le récepteur ACE2 humain, les interactions du domaine N terminal avec les récepteurs du glycane à base d’acide sialique qui tapissent les voies respiratoires sont importantes pour déclencher sa liaison à l’ACE2. Toutefois, les déterminants structurels de cette reconnaissance demeurent insaisissables. Comme les détails atomiques de ces interactions pourraient être exploités pour concevoir et optimiser des médicaments expérimentaux, le bénéficiaire déterminera une série de structures cristallines de domaines des spicules complexés avec divers peptides dérivés de l’ACE2 et des glucides de glycanes. Les données structurelles générées constitueront une base solide pour la poursuite de l’ingénierie des peptides et des glycanes avec des améliorations progressives des propriétés de liaison et de neutralisation de la protéine de spicule du SRAS-CoV-2, ouvrant la voie au développement de médicaments expérimentaux qui peuvent répondre non seulement à la pandémie actuelle, mais aussi aux défis que nous réserve l’avenir.
