Citation | Journal: Proc Natl Acad Sci U S A / Year: 2021 Title: The effect of the D614G substitution on the structure of the spike glycoprotein of SARS-CoV-2. Authors: Donald J Benton / Antoni G Wrobel / Chloë Roustan / Annabel Borg / Pengqi Xu / Stephen R Martin / Peter B Rosenthal / John J Skehel / Steven J Gamblin / Abstract: The majority of currently circulating severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) viruses have mutant spike glycoproteins that contain the D614G substitution. Several studies have ...The majority of currently circulating severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) viruses have mutant spike glycoproteins that contain the D614G substitution. Several studies have suggested that spikes with this substitution are associated with higher virus infectivity. We use cryo-electron microscopy to compare G614 and D614 spikes and show that the G614 mutant spike adopts a range of more open conformations that may facilitate binding to the SARS-CoV-2 receptor, ACE2, and the subsequent structural rearrangements required for viral membrane fusion. | |||||||||
