Erythrocyte transketolase activity in uremia

Clinica Chimica Acta, 1980
We performed a study concerning the activity of erythrocyte transketolase and thiamine metabolism in 73 uremic patients with or without neuropathy and 67 normal control subjects. Although the total vitamin B1 level in whole blood was high in the uremic patients, the transketolase activity in the hemolysate and the thiamine pyrophosphate effect on it ...

One-Substrate Transketolase-Catalyzed Reaction

Biochemical and Biophysical Research Communications, 2001
Apart from catalyzing the common two-substrate reaction with ketose as donor substrate and aldose as acceptor substrate, transketolase is also able to catalyze a one-substrate reaction utilizing only ketose (xylulose 5-phosphate) as substrate. The products of this one-substrate reaction were glyceraldehyde 3-phosphate and erythrulose.

Analysis of Blood Transketolase Activity

American Journal of Clinical Pathology, 1971
The determination of blood transketolase (TK) activity is based on the incubation of lysed erythrocytes with and without added thiamine pyrophosphate (TPP). The increased TK activity resulting from the addition of TPP coenzyme is inversely related to thiamine depletion.

Sulfhydryl groups and transketolase activity

Biochemical and Biophysical Research Communications, 1966
Abstract Transketolase, an enzyme of pentose cycle, catalyzes the reaction of glycolaldehyde transport from the xylulose-5-phosphate to the ribose-5-phosphate with the formation of sedoheptulose-7-phosphate. There is not much known about this enzyme, especially in respect to its functional groups.

Anaemia and Erythrocyte Transketolase Activity

Acta Haematologica, 1972
Erythrocyte transketolase activity is raised in megaloblastic anaemia due to vitamin B12 deficiency and inversely related to haemoglobin concentration.

Transketolase Activity in Uremia

Archives of Internal Medicine, 1970
Erythrocyte transketolase activity (ETKA) was determined in ten uremics undergoing long-term hemodialysis and in four patients treated with Giordano-Giovanetti diet therapy. Transketolase is an essential enzyme in the pentose phosphate shunt and plays a role in myelin sheath maintenance. Its co-factor is thiamine pyrophosphate.

Donor substrate regulation of transketolase

European Journal of Biochemistry, 2004
The influence of substrates on the interaction of apotransketolase with thiamin diphosphate was investigated in the presence of magnesium ions. It was shown that the donor substrates, but not the acceptor substrates, enhance the affinity of the coenzyme either to only one active center of transketolase or to both active centers, but to different ...

Variants of transketolase from human erythrocytes

Clinica Chimica Acta, 1983
Analytical isoelectric focusing and a stain for transketolase have been applied to partially purified samples of human erythrocyte hemolysates and have detected individual species of transketolase having pI values of 6.6, 7.3, 7.5, 7.8, 8.1, 8.2, 8.4 and 9.2. Six different patterns of these species were detected in 25 healthy subjects.
