Abstract Coronavirus disease 2019 (COVID-19) has been an ongoing global pandemic for
over a year. Recently, an emergent SARS-CoV-2 variant (B. 1.1. 7) with an unusually large …

The recent emergence of novel SARS-CoV-2 variants has threatened the efforts to contain
the COVID-19 pandemic. The emergence of these “variants of concern” has increased …

Some recent SARS-CoV-2 variants appear to have increased transmissibility compared to
the original strain. An underlying mechanism could be the improved ability of the variants to …

Abstract Background Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) has
caused millions of infections and deaths worldwide since its discovery in late 2019 in …

ABSTRACT SARS-CoV-2 is spreading around the world for the past year. Enormous efforts
have been taken to understand its mechanism of transmission. It is well established now that …

The increasing number of SARS-CoV-2 variants associated with highly transmissible
phenotypes is a health-public concern in the current pandemic scenario. Herein, we …

The receptor-binding domain (RBD) of the SARS-CoV-2 spike protein plays a crucial role in
binding the human cell receptor ACE2 that is required for viral entry. Many studies have …

Since the worldwide outbreak of the infectious disease COVID-19, several studies have
been published to understand the structural mechanism of the novel coronavirus SARS-CoV …

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infects human cells by
binding its spike (S) glycoproteins to angiotensin-converting enzyme 2 (ACE2) receptors …

SARS-CoV and SARS-CoV-2 bind to the human ACE2 receptor in practically identical
conformations, although several residues of the receptor-binding domain (RBD) differ …
