Figure 2From: Molecular characterization and determination of the biochemical properties of cathepsin L of Trichinella spiralisMultiple alignment and sequence logo identification of cathepsin L. Identical and similar residues are labelled with blue shading. Putative active site residues (Gln [Q], Cys [C], His [H] and Asn [N]) are labelled with red triangles. Substrate-binding pocket residues (Leu [L], Met [M], Ala [A], Leu [L], Gly [G] and Phe [F]) are labelled with black arrows, and the ERFNIN, GYLND and GCN/SGG motifs are labelled with yellow boxes.Back to article page
