The active centre of triose phosphate isomerase.
The molecular weight and amino acid composition of triose phosphate isomerase have been determined. The molecular weight (43000) is lower and the molecular activity (500000) higher than those of most other glycolytic enzymes. Reaction with iodoacetate (studied with radioactive reagent) takes place in two phases: in the first phase, at pH6.3, cysteine and methionine groups react and enzymic acti...
متن کاملErythrocyte lipids in triose-phosphate isomerase deficiency.
Marked hypoalphalipoproteinemia was found together with relatively low serum cholesterol, triacylglycerol, and LDL levels in a triose-phosphate isomerase (TPI; D-glyceraldehyde-3-phosphate ketol-isomerase, EC 5.3.1.1)-deficient Hungarian family, especially in the two compound-heterozygote brothers. Apart from a slight increase in palmitic and stearic acids together with a slight decrease in ole...
متن کاملThermolabile triose phosphate isomerase in a psychrophilic Clostridium.
The psychrophile Clostridium sp. strain 69 contains a thermolabile triose phosphate isomerase which is inactivated rapidly in vitro and in vivo at 32 C.
متن کاملDegradation of functional triose phosphate isomerase protein underlies sugarkill pathology.
Triose phosphate isomerase (TPI) deficiency glycolytic enzymopathy is a progressive neurodegenerative condition that remains poorly understood. The disease is caused exclusively by specific missense mutations affecting the TPI protein and clinically features hemolytic anemia, adult-onset neurological impairment, degeneration, and reduced longevity. TPI has a well-characterized role in glycolysi...
متن کاملDisequilibrium in the triose phosphate isomerase system in rat liver.
1. The equilibrium constant at 38 degrees and I 0.25 of the triose phosphate isomerase reaction was found to be 22.0 and that of the aldolase reaction, 0.99x10(-4)m. The [dihydroxyacetone phosphate]/[glyceraldehyde phosphate] ratio was found to be 9.3 in rat liver. The causes of the apparent deviation of the triose phosphate isomerase system from equilibrium in vivo have been investigated. 2. T...
