Triosephosphate isomerase (EC:5.3.1.1) (TIM) [1] is the glycolytic enzyme that catalyses 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 [2,3]. The tertiary structure of TIM has eight beta/alpha motifs folded into a barrel structure [4]. 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 [5].	Domain
