This gene encodes a thiamine-dependent enzyme which plays a role in the channeling of excess sugar phosphates to glycolysis in the pentose phosphate pathway. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene. [provided by RefSeq, Apr 2012] (from NCBI)

Papers on transketolase
A thermostable transketolase evolved for aliphatic aldehyde acceptors.
Fessner et al., Darmstadt, Germany. In Chem Commun (camb), 11 Feb 2015
Directed evolution of the thermostable transketolase from Geobacillus stearothermophilus based on a pH-based colorimetric screening of smart libraries yielded several mutants with up to 16-fold higher activity for aliphatic aldehydes and high enantioselectivity (>95% ee) in the asymmetric carboligation step.

Apte et al., Mumbai, India. In Proteomics, 21 Nov 2014
However, remarkably decreased levels of key metabolic enzymes (aconitase, transketolase, 3-hydroxy acyl-CoA dehydrogenase, acyl-CoA dehydrogenase, electron transfer flavoprotein alpha and beta) involved in carbon and energy metabolism were observed upon tellurite stress.
Cloning of the transketolase gene from erythritol-producing yeast Candida magnoliae.
Kim et al., Ch'unch'ŏn, South Korea. In J Microbiol Biotechnol, Oct 2014
The entire nucleotide sequence of the TKL1 gene encoding transketolase (TKL) in an erythritolproducing yeast of Candida magnoliae was determined by degenerate polymerase chain reaction and genome walking.
Structure and functioning mechanism of transketolase.
Solovjeva et al., Moscow, Russia. In Biochim Biophys Acta, Sep 2014
Transketolase, discovered independently by Racker and Horecker in 1953 (and named by Racker) [1], did not receive much attention until 1992, when crystal X-ray structure analysis of the enzyme from Saccharomyces cerevisiae was performed [2].
Engineering stereoselectivity of ThDP-dependent enzymes.
Pohl et al., London, United Kingdom. In Febs J, Dec 2013
Both structurally different enzyme families differ also in stereoselectivity: enzymes from the decarboxylase family are predominantly R-selective, whereas those from the transketolase family are S-selective.
Using site-saturation mutagenesis to explore mechanism and substrate specificity in thiamin diphosphate-dependent enzymes.
McLeish et al., Indianapolis, United States. In Febs J, Dec 2013
We also summarize the results obtained when SSM was used to evolve new substrate specificity and/or enantioselectivity in ThDP-dependent enzymes such as benzoylformate decarboxylase, transketolase, 2-succinyl-5-enolpyruvyl-6-hydroxy-3-cyclohexene-1-carboxylate synthase and the E1 component of the 2-oxoglutarate dehydrogenase complex.
[Vitamin B1 (thiamine)].
Guilland, Dijon, France. In Rev Prat, Oct 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.
Sub-ångström-resolution crystallography reveals physical distortions that enhance reactivity of a covalent enzymatic intermediate.
Tittmann et al., Göttingen, Germany. In Nat Chem, Sep 2013
Here, we report sub-ångström-resolution crystal structures of genuine covalent reaction intermediates of transketolase.
The role of thiamine in cancer: possible genetic and cellular signaling mechanisms.
Nguyễn et al., Westminster, United States. In Cancer Genomics Proteomics, Jul 2013
Genetic studies have helped identify a number of factors that link thiamine to cancer, including the solute carrier transporter (SLC19) gene, transketolase, transcription factor p53, poly(ADP-ribose) polymerase-1 gene, and the reduced form of nicotinamide adenine dinucleotide phosphate.

Benfotiamine blocks three major pathways of hyperglycemic damage and prevents experimental diabetic retinopathy.
Brownlee et al., Mannheim, Germany. In Nat Med, 2003
We have discovered that the lipid-soluble thiamine derivative benfotiamine can inhibit these three pathways, as well as hyperglycemia-associated NF-kappaB activation, by activating the pentose phosphate pathway enzyme transketolase, which converts glyceraldehyde-3-phosphate and fructose-6-phosphate into pentose-5-phosphates and other sugars.
