Protein Name: Triosephosphate isomerase

UniprotKB/SwissProt ID: P48500 (P48500)

Gene Name: Tpi1

Organism: Rattus norvegicus (Rat)

Function: Triosephosphate isomerase is an extremely efficient metabolic enzyme that catalyzes the interconversion between dihydroxyacetone phosphate (DHAP) and D-glyceraldehyde-3-phosphate (G3P) in glycolysis and gluconeogenesis It is also responsible for the non-negligible production of methylglyoxal a reactive cytotoxic side-product that modifies and can alter proteins, DNA and lipids

Other Modifications: View all modification sites in dbPTM

Protein Subcellular Localization: Cytoplasm
