Figure 4
Electrostatic surface plots of bovine (a) and camel (b) chymosin oriented with the C-terminal domain to the left and the N-terminal domain to the right, looking into the binding cleft (top) and rotated 180° around the horizontal direction (bottom). The scales indicate the charge in kBT/ec. The box shows the sequence of the charged patches; their corresponding positions on the surface are marked in (a) and (b). |
