Triosephosphate isomerase is an enzyme that in humans is encoded by the TPI1 gene. This gene encodes an enzyme, consisting of two identical proteins, which catalyzes the isomerization of glyceraldehyde 3-phosphate (G3P) and dihydroxyacetone phosphate (DHAP) in glycolysis and gluconeogenesis .
Triosephosphate isomerase deficiency is a rare autosomal recessive [2] metabolic disorder which was initially described in 1965. [3]It is a unique glycolytic enzymopathy that is characterized by chronic haemolytic anaemia, cardiomyopathy, susceptibility to infections, severe neurological dysfunction, and, in most cases, death in early childhood.

The usual pathway converting GAP to pyruvate starts with the enzyme glyceraldehyde 3-phosphate dehydrogenase (Weber 711–13). Low phosphate levels inhibit GAP dehydrogenase; GAP is instead converted into DHAP by triosephosphate isomerase. Again, increased levels of DHAP activate methylglyoxal synthase and methylglyoxal production (Weber 711–13).
The TIM barrel (triose-phosphate isomerase), also known as an alpha/beta barrel, [1]: 252 is a conserved protein fold consisting of eight alpha helices (α-helices) and eight parallel beta strands (β-strands) that alternate along the peptide backbone. [2] The structure is named after triose-phosphate isomerase, a conserved metabolic enzyme. [3]

As a person living with latent autoimmune diabetes in adults (aka LADA), I know how much of an impact diet can have on my blood sugar management. So, when I decided to try a plant-based diet for ...
