Molecular insights into receptor binding energetics and neutralization of SARS-CoV-2 variants
Abstract
Here, the authors combine single-molecule atomic force spectroscopy measurements and molecular dynamics simulations to investigate the binding of spike proteins from four SARS-CoV-2 variants of concern (VoC) to the human ACE2 receptor. They observe an increase in the RBD-ACE2 complex stability for several of the VoCs and derive how the mutations affect the kinetic, thermodynamic and structural properties of complex formation.
