Triosephosphate isomerase structure

WebDec 1, 2009 · Abstract. The triosephosphate isomerase (TPI) functions at a metabolic cross-road ensuring the rapid equilibration of the triosephosphates produced by aldolase in glycolysis, which is interconnected to lipid metabolism, to glycerol-3-phosphate shuttle and to the pentose phosphate pathway. The enzyme is a stable homodimer, which is … WebTriosephosphate isomerase (TPI) is a glycolytic enzyme that catalyzes the interconversion of dihydroxyacetone phosphate (DHAP) and glyceraldehyde-3 phosphate (Fig. 17.12 ). Missense mutations within the gene TPI, encoded at chromosome 12p13, lead to an autosomal recessive disorder known as TPI deficiency. 409,410 The deficiency of TPI …
