The novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that has recently caused the current outbreak of COVID-19, shares many similarities with the SARS coronavirus of 2002-2003 (SARS-CoV), including 76% amino acid sequence identity in the spike protein. A key to tackling the current pandemic is to understand the receptor recognition mechanism of the virus, which regulates its infectivity and pathogenesis. The binding affinity of SARS-CoV-2 with the ACE2 receptor is stronger than SARS-CoV and may explain the larger global influence of COVID-19 than the initial SARS outbreak.
I created this two-page illustration for a popular science magazine to highlight how amino acid changes to the viral sequences may ultimately affect spike protein binding affinity to the ACE2 receptor at the molecular level.
