Concanavalin A targeting N-linked glycans in spike proteins influence viral interactions

Dalton Trans. 2020 Oct 12;49(39):13538-13543. doi: 10.1039/d0dt02932g.

Abstract

Lectins, which exhibit viral-interaction abilities, have garnered attention in the current pandemic era as potential neutralizing agents and vaccine candidates. Viral invasion through envelope proteins is modulated by N-linked glycosylation in the spike (S) protein. This study demonstrates the biophysical aspects between lectins and high-mannose and -galactose N-glycans to provide insights into binding events.
