Substrate inhibition of transketolase.
Moscow, Russia. In Biochim Biophys Acta, Jan 2016
UNASSIGNED: We studied the influence of the acceptor substrate of transketolase on the activity of the enzyme in the presence of reductants.

Ulm, Germany. In Internist (berl), Nov 2015
Most prevalent are deficiencies in vitamin B1, vitamin B12, and vitamin D. Serum levels are often misleading and show false negative results in vitamin B1 and B12 deficiencies; therefore, determination of erythrocyte transketolase activity (ETKA) and the thiamine pyrophosphate (TPP) effect for vitamin B1 and of methylmalonic acid and holotranscobalamine for vitamin B12 is recommended.
Structure and functioning mechanism of transketolase.
Moscow, Russia. In Biochim Biophys Acta, 2014
Transketolase, discovered independently by Racker and Horecker in 1953 (and named by Racker) , did not receive much attention until 1992, when crystal X-ray structure analysis of the enzyme from Saccharomyces cerevisiae was performed .
[Vitamin B1 (thiamine)].
Dijon, France. In Rev Prat, 2013
The biological exploration of vitamin B1 status is based on the measurement of thiamine pyrophosphate concentration or of the activity of a thiamine-dependent enzyme, transketolase, in erythrocytes.
Riboneogenesis in yeast.
Princeton, United States. In Cell, 2011
Riboneogenesis begins with synthesis, by the combined action of transketolase and aldolase, of the seven-carbon bisphosphorylated sugar sedoheptulose-1,7-bisphosphate.
The effect of acetaldehyde on human brain transketolase activity.
London, United Kingdom. In Addict Biol, 1997
In the present investigation the direct effect of ACH was studied on the activity of transketolase, a thiaminedependent enzyme, as well as two non-thiamine-dependent enzymes (aspartate aminotransferase and lactate dehydrogenase), isolated from five control human brains.
