Figure 4From: Structure of catalytic domain of Matriptase in complex with Sunflower trypsin inhibitor-1Solvent-accessible surfaces of (A) matriptase and (B) trypsin are colored by electrostatic potential (-7 to +7 kT/e in blue to red) computed by APBS [48]. The matriptase active site surface is more acidic than that of trypsin.Back to article page
