Fig. 6From: Bioinformatics analysis and characterization of a secretory cystatin from Thelohanellus kitaueiInteraction between TK-cystatin and proteases. a papain (PDB ID: 1ppp), b cathepsin L (PDB ID: 2NDQ), c cathepsin B (PDB ID: 1GMY). TK-cystatin was shown in green and three cysteine proteases were shown in blue. The hydrogen and salt bonds formed between the conserved site of TK-cystatin and three proteases were shown in orange and magenta, respectivelyBack to article page
