Figure 3From: Bioinformatic analysis of the neprilysin (M13) family of peptidases reveals complex evolutionary and functional relationshipsUtilisation of residues by ligand binding subsites of M13 peptidases. The utilisation of the twenty amino acids in both the S1' and S2' subsites was examined. The percentage contribution of each amino acid to either binding site was calculated and residues were placed in the order of descending frequency for the S1' subsite.Back to article page
