Triosephosphate isomerase

Triosephosphate isomerase (TPI) is a key glycolytic enzyme that catalyzes the reversible isomerization of dihydroxyacetone phosphate and glyceraldehyde-3-phosphate. This dimeric enzyme, with its active site at the subunit interface, is essential for energy metabolism and is widely used in studies of glycolysis, enzymology, and metabolic disorders in both biochemical and cellular research.
