Target Background |
SARS-CoV-2 (Severe Acute Respiratory Syndrome Coronavirus 2) also known as 2019-nCoV (2019 Novel Coronavirus) is a virus that causes illnesses ranging from the common cold to severe diseases. The spike protein mutation N501Y is one of six key contact residues within the receptor-binding domain (RBD) andhas been identified as increasing binding affinity to human and murine ACE2. |
