Electrostatic surfaces potential of HaSCP-2 and the hydrophobicity of ligand-binding cavity.

(A) Negative surface potentials are in red, positive surface potentials are in blue and neutral surface potentials are in white. The orientation of SCP-2 in left is corresponding to that in Fig. 4. This side of the molecule is referred to as the front-side and the orientation of SCP-2 in right was obtained by a 180° clockwise rotation about a vertical axis in the plane of the paper. The green arrows showed the proposed tunnel with putative entrance and exit. (B) the 18 hydrophobic amino acids within the interior surface of the ligand-binding cavity found by siteID Find Pocket program in SYBYL software.
