	Triosephosphateisomerase - Wikipedia, the free encyclopedia
		Triose-phosphate isomerase (TPI), is an enzyme (EC 5.3.1.1) that catalyzes the reversible interconversion of triose phosphates isomers dihydroxyacetone phosphate and D-glyceraldehyde 3-phosphate.
		Triose phosphate isomerase is a massively efficient enzyme, performing the reaction billions of times faster than it would naturally in solution.
		Triose phosphate isomerase is a dimer of identical subunits, each of which is made up of about 250 amino acid residues.

	Photosynthetic carbon reduction
		The GAP made initially is converted by triose phosphate isomerase to dihydroxyacetone phosphate (DHAP) (perhaps this compound is more properly a bis hydroxy, since the hydroxyls are attached to different carbons but this term is never used).
		Some of the triose phosphate made can be stored temporarily as starch inside the chloroplast, but generally this accounts for half or less of the carbon fixed in photosynthesis.
		As photosynthesis proceeds, the concentration of phosphate falls as triose phosphate is produced.

	Pyruvate
		Arm endurance was significantly improved by 20% (160 minutes) for the triose supplemented group compared to the placebo group (133 minutes).
		The triose group had greater pre-exercise triceps glycogen stores (130 mmol/kg) compared to the placebo group (88 mmol/kg).
		In one study (see Stanko, 1992), 13 subjects consumed either a 500 calorie placebo diet (60% carbohydrate, 40% protein) or a 500 calorie treatment diet (28 g mixture of pyruvate and DHA were isocalorically substituted for glucose).

		For analysis of undifferentiated three-carbon fragments of glucose, the isolated glucose was reduced to sorbitol using sodium borohydride in anhydrous dimethyl sulfoxide (30) and then peracetylated with acetic anhydride/pyridine.
		Carbons 1-3 are indistinguishable from carbons 4-6 in the triose fragment in the mass spectrum(31).
		Many, but not all, studies have indicated that isotopic equilibrium is present between the triose phosphates(7, 32), based on comparisons of labeling in glucose carbons 1-3 (representing DHAP) and carbons 4-6 (representing glyceraldehyde-3-phosphate).

		Since 5/6 of triose phosphate synthesized in photosynthesis is needed for regeneration of RuBP, a maximum of 1/6 of triose phosphate formed is available for synthesis of fructose and other molecules in the cytoplasm.
		These triose phosphates can be utilized in respiration, in the synthesis of other molecules in plants such as lipids or for synthesis of sucrose.
		While this may be true in the light, the export of assimilate from transient starch turnover in chloroplasts in the dark appears to be predominately in the form of glucose as indicated in these studies.

		The resulting triose phosphates produced can supply carbon to leaf cells or be converted to sucrose for export to other parts of the plant.
		One is composed of hexose phosphates, the other of pentose phosphate pathway intermediates and the triose phosphates glyceraldehyde 3-phosphate and dihydroxyacetone phosphate.
		When viewed as only one of many pathways linking the hexose phosphate and triose phosphate/pentose phosphate pools, glycolysis is revealed as a set of reactions contributing to an integrated whole plant metabolism rather than a discrete pathway to be memorized and quickly forgotten.

	Triose Phosphate
		Triose phosphate isomerase (TIM) was selected to represent intramolecular oxidoreductases that catalyze the oxidation of one part of a molecule by the reduction of another part. In glycolysis dihydroxyacetone phosphate (DHAP) and D-glyceraldehyde-3-phosphate (GAP) are readily interconverted for glycolitic purposes.
		Deficiency in triose phophate isomerase leads to high levels of dihydroxyacetone which can cause severe anemia and neourmuscular impairment.
		The TIM barrel enzymes usually have the active site at the C-terminal end of the beta-barrel and triose phosphate isomerase is no exception.

		Remember as stated in the web notes for lecture 7, the utilization of triose phosphate generated by photosynthesis in starch, sucrose and/or fructan synthesis is tightly controlled (see Chapt.
		Both triose phosphate and glucose export from plastids contribute to the cytosolic glucose and fructose for sucrose synthesis and Pi for photosynthetic reactions (see also the answer to the question posted 2/11/99).
		Thus it would be expected that increased sucrose phosphate synthase would increase photosynthesis up to the point that triose phosphate formation becomes limiting.

	Triose Phosphate Isomerase: Genetic Music
		When glucose is metabolized for energy, one of the early steps is the breaking of the six-carbon glucose diphosphate into two three-carbon sugars or trioses.
		One of the two sugars is glyceraldehyde-3-phosphate and the other is a related sugar that can be converted to glyceraldehyde-3-phosphate by the action of triose phosphate isomerase.
		The music begins with a slow section that samples the amino acids of the protein at fairly long intervals.

		After trying out other musicians and nothing really working out (there is actually a demo out there of the short-lived band Dose), Frank had the epiphany that he must play bass (and might I say it just couldn't be any other way!), thusly forming Triose.
