Interaction surface between KLK4 and K41043. The residues within 4 Å of SPINK2 in the molecular surface of KLK4 are colored in yellow and orange; orange colored region are within the S1 pocket. The green cartoon model indicates K41043. The colored amino acid numbers and residues are shown below. Asterisks (*) indicate catalytic residues of KLK4.
