3D structure model of TPG1. In a and c, the N-terminus of the protein is on the right and in b, it is in front. Conserved motifs are shown in color and/or in balls-and-sticks: catalytic residues QDD are in green and GHG in blue; substrate binding residues RIK are in orange and NTD in yellow. Conserved cysteine residues are shown in red balls-and-sticks in c. AT, amino terminus; CT, carboxyl terminus
