Journal ArticleDOI
Receptor binding and priming of the spike protein of SARS-CoV-2 for membrane fusion.
D.J. Benton,A.G. Wrobel,Pengqi Xu,Pengqi Xu,Chloe Roustan,Stephen R. Martin,Peter B. Rosenthal,John J. Skehel,Steven J. Gamblin +8 more
TL;DR: Cryo-electron microscopy structures of consecutive binding events of ACE2 in complex with the spikeprotein of SARS-CoV-2 reveal the mechanisms of receptor binding by the spike protein and activation for membrane fusion by the Spike protein of Sars-Co V-2.
Journal ArticleDOI
SARS-CoV-2 and bat RaTG13 spike glycoprotein structures inform on virus evolution and furin-cleavage effects.
A.G. Wrobel,D.J. Benton,Pengqi Xu,Pengqi Xu,Chloe Roustan,Stephen R. Martin,Peter B. Rosenthal,John J. Skehel,Steven J. Gamblin +8 more
TL;DR: Cryo-EM and functional analyses of furin-cleaved spike from SARS-CoV-2 and the closely related spike from bat virus RaTG13 reveal differences in protein stability and binding to human receptor ACE2.
Journal ArticleDOI
The effect of the D614G substitution on the structure of the spike glycoprotein of SARS-CoV-2.
D.J. Benton,A.G. Wrobel,Chloe Roustan,Annabel Borg,Pengqi Xu,Stephen R. Martin,Peter B. Rosenthal,John J. Skehel,Steven J. Gamblin +8 more
TL;DR: In this paper, the authors used cryo-electron microscopy to compare G614 and D614 spikes and showed that the G614 mutant spike adopts a range of more open conformations that may facilitate binding to the SARS-CoV-2 receptor, ACE2, and subsequent structural rearrangements required for viral membrane fusion.
Journal ArticleDOI
Molecular insights into Zeaxanthin-dependent quenching in higher plants
TL;DR: Zeaxanthin is acting in between the complexes, helping to create/participating in a variety of quenching sites, which can explain why none of the antennas appears to be essential for NPQ and the multiple quench mechanisms that have been observed in plants.
Journal ArticleDOI
Single-Molecule Identification of Quenched and Unquenched States of LHCII.
Gabriela S. Schlau-Cohen,Hsiang-Yu Yang,Tjaart P. J. Krüger,Pengqi Xu,Michal Gwizdala,Rienk van Grondelle,Roberta Croce,W. E. Moerner +7 more
TL;DR: The results suggest that there are at least two distinct quenching sites with different molecular compositions, meaning multiple dissipative pathways in LHCII, and one of the quenched conformations significantly increases in relative population under environmental conditions mimicking high light.
