Figure 1

Electrostatic surface potential of (a) human cationic trypsinogen (“WT”) in comparison to (b) modeled guinea pig trypsinogen (“GP”) and (c) modified human trypsinogen (“sc”). The range of electrostatic surface potential is shown from -7 kT/e (red color) to +7 kT/e (blue color). N-terminal amino acids (V25 based on structure of trypsinogen 1TGN) are marked with a black circle. The substrate-binding cleft is located on the rear side of the shown model structures.
