Fig. 5From: Bioinformatics analysis and characterization of a secretory cystatin from Thelohanellus kitaueiThree-dimensional structure of TK-cystatin. Its 3D structure showed the typical wedge-shaped structure of cysteine protease inhibitor. The deep purple arrows pointed to the N- terminus or C-terminus of TK-cystatin. The position of the conserved motif in the 3D structure was shown by a magenta stick, next to the residue namesBack to article page
