Triosephosphate isomerase
Triosephosphate isomerase (EC:5.3.1.1) (TIM) is the glycolytic enzyme that catalyzes the reversible interconversion of glyceraldehyde 3-phosphate and dihydroxyacetone phosphate. TIM plays an important role in several metabolic pathways and is essential for efficient energy production, present in eukaryotes and prokaryotes. TIM is a dimer of identical subunits, each of which is made up of about 250 amino-acid residues. A glutamic acid residue is involved in the catalytic mechanism. The tertiary structure of TIM has eight beta/alpha motifs folded into a barrel structure. The sequence around the active site residue is perfectly conserved in all known TIM's. Deficiencies in TIM are associated with haemolytic anaemia coupled with a progressive, severe neurological disorder.
