(RBD) and the ACE2 cell surface protein is required for viral infection of cells. Mutations in
the RBD are present in SARS-CoV-2 variants of concern that have emerged independently …

The spread of COVID-19 caused by the SARS-CoV-2 outbreak has been growing since its
first identification in December 2019. The publishing of the first SARS-CoV-2 genome made …

Abstract SARS-CoV-2 recognizes, via its spike receptor-binding domain (S-RBD), human
angiotensin-converting enzyme 2 (ACE2) to initiate infection. Ecto-domain protein of ACE2 …

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 …

Summary The coronavirus disease 2019 (COVID-19) pandemic continues worldwide with
many variants arising, some of which are variants of concern (VOCs). A recent VOC, omicron …

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 current pandemic of COVID-19 is caused by a novel coronavirus, severe acute
respiratory syndrome coronavirus 2 (SARS-CoV-2). The SARS-CoV-2 spike protein receptor …

The recognition of ACE2 by the receptor-binding domain (RBD) of spike protein mediates
host cell entry. The objective of the work is to identify SARS-CoV2 spike variants that …

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 …

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 …
