Fig. 3From: Oral cavity infection by the SARS-CoV-2: emphasizing the essence of masking and peptide therapeuticsPeptide-based inhibition of the TMPRSS2 using the molecular docking protocol. a displays a surface representation of TMPRSS2 (blue) and the catalytic domain was distinguished using purple coloration. b Represent the designed therapeutic peptide with each residue shown in different colors and labeled according to the sequence of arrangement. Lys-1, Arg-2 and Ser-3 are all colored in red, green and yellow, respectively. c A display of the molecular docking result showing TMPRSS2 (surface) in a complex with the designed therapeutic peptideBack to article page
