Transketolase

transketolase
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)

Structure and functioning mechanism of transketolase.
Review
New
Solovjeva et al., Moscow, Russia. In Biochim Biophys Acta, 30 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.
Review
New
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.
Review
New
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.
Conference report: 9th international summer school of neurology.

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.

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.
