Structural and Functional Analysis of the D614G SARS-CoV-2 Spike Protein Variant.

TLDR
It is shown that D614G was more infectious than the ancestral form on human lung cells, colon cells, and on cells rendered permissive by ectopic expression of human ACE2 or of ACE2 orthologs from various mammals, including Chinese rufous horseshoe bat and Malayan pangolin.

SARS-CoV-2 variants, spike mutations and immune escape.

TL;DR: A review of the literature on mutations of the SARS-CoV-2 spike protein, the primary antigen, focusing on their impacts on antigenicity and contextualizing them in the protein structure is presented in this article.
Journal ArticleDOI

Spike mutation D614G alters SARS-CoV-2 fitness.

TL;DR: Hamsters infected with SARS-CoV-2 expressing spike D614G (G614 virus) produced higher infectious titres in nasal washes and the trachea, but not in the lungs, supporting clinical evidence showing that the mutation enhances viral loads in the upper respiratory tract of COVID-19 patients and may increase transmission.

Detection of a SARS-CoV-2 variant of concern in South Africa.

TL;DR: A newly arisen lineage of SARS-CoV-2 (designated 501Y.V2) was identified in South Africa after the first wave of the epidemic in a severely affected metropolitan area (Nelson Mandela Bay) that is located on the coast of the Eastern Cape province.
Journal ArticleDOI

Mechanisms of SARS-CoV-2 entry into cells.

TL;DR: In this article, structural and cellular foundations for understanding the multistep SARS-CoV-2 entry process, including S protein synthesis, S protein structure, conformational transitions necessary for association of the spike (S) protein with ACE2, engagement of the receptor-binding domain of the S protein with ACS, proteolytic activation of S protein, endocytosis and membrane fusion are provided.

Improving biosensor analysis.

TL;DR: It is possible to globally fit high‐quality biosensor data with simple bimolecular reaction models, which validates the technology as a biophysical tool for interaction analysis.

Evolutionary origins of the SARS-CoV-2 sarbecovirus lineage responsible for the COVID-19 pandemic.

TL;DR: SARS-CoV-2 itself is not a recombinant of any sarbecoviruses detected to date, and its receptor-binding motif appears to be an ancestral trait shared with bat viruses and not one acquired recently via recombination.

Cryo-EM structures of MERS-CoV and SARS-CoV spike glycoproteins reveal the dynamic receptor binding domains

TL;DR: High-resolution structures of the trimeric MERS- coV and SARS-CoV S proteins in its pre-fusion conformation are presented by single particle cryo-electron microscopy, demonstrating an inherently flexible RBD readily recognized by the receptor.
