Abstract
This research paper investigates the structure and dynamics of full-length coronavirus spikes, focusing on their correlation with virus infectivity. Using cryo-electron tomography (cryoET) and mass spectrometry, the study reveals the conformational landscape of human coronavirus NL63 (HCoV-NL63) spikes on intact virions. The findings highlight the role of hinge glycans in modulating spike bending, specifically identifying N1242 glycosylation as crucial for spike crown orientational freedom and virus entry. These results suggest a potential therapeutic target for HCoV-NL63.
