Fig. 4From: Oral cavity infection by the SARS-CoV-2: emphasizing the essence of masking and peptide therapeuticsA 2D representation of the predicted interactions as a result of the therapeutic peptide binding to the catalytic domain of TMPRSS2 upon docking. Residues of the therapeutic peptide are labeled in blue color while their interacting partners (catalytic domain residues of TMPRSS2) are labeled in green colorBack to article page
