More model informationTriosephosphate isomerase (TPI) is a homodimeric enzyme found in all living organisms. Its plays a crucial role in the glycolysis pathway. It is found in all cells that undergo glycolysis. The primary function of TPI is to catalyze the isomerization of dihydroxyacetone phosphate (DHAP) into glyceraldehyde-3-phosphate (G3P). There are three key amino acid residues that make up the active site of TPI (glu165, his95, and lys13). This model shows TPI and the interaction between the active site and the ligand 2-phosphoglycolic acid (PGA).
