A 2D depiction of the predicted interaction between surface residues of the TMPRSS2-PAI-1 protein complex. Residues shown in the upper layer of the figure (colored green) denote the catalytic domain residues of TMPRSS2 while the lower layer residues denote the interacting surface residues of PAI-1. Each residue is named sequentially based on a combination of the 3-letter amino acid code, position, and chain
