Figure 4From: MPRAP: An accessibility predictor for a-helical transmem-brane proteins that performs well inside and outside the membraneIdentification of interface residues. Identification of interface residues among residues exposed in a single protein chain. For all these residues MPRAP was used to predict its accessibility. At a given MPRAP cutoff the fraction of all interface residues predicted to have accessibility less than the cutoff is plotted against the fraction non-interface residues above this cutoff.Back to article page
