Fig. 1. The S-protein in SARS-CoV-2 (6VSB) divided into two subunits S1 and S2 with their domains. The missing position coordinates are indicated by vertical black lines with their sequence numbers shown in grey boxes pointed with dashed arrows. The overall number of amino acids, atoms and their sequence number range are marked in upper part of the horizontal bar. The numbers at the bottom of the horizontal bar show the sequence numbers for the domains with their respective color.
