triosephosphate isomerase


Also found in: Wikipedia.

tri·ose·phos·phate i·som·er·ase

(trī'ōs-fos'fāt ī-som'ĕr-ās),
An isomerizing enzyme that catalyzes the reversible interconversion of d-glyceraldehyde 3-phosphate and dihydroxyacetone phosphate, a reaction of importance in glycolysis and gluconeogenesis; a deficiency of this enzyme will result in hemolytic anemia and severe neurologic deficits.

To our knowledge, only a limited number of enzymes with such catalytic carboxyl group(s) are known so far in other groups of enzymes than hydrolases and transferases, such as triosephosphate isomerase (catalytic Glu), (201) glucosamine 6-phosphate isomerase (or deaminase) (catalytic Asp), (202) phosphofructokinase (catalytic Asp) 203) etc., where the catalytic Glu/Asp residues are also thought to function as general acid/bases.
