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)

Oral cancer cells may rewire alternative metabolic pathways to survive from siRNA silencing of metabolic enzymes.
New
Hu et al., In Bmc Cancer, 25 Apr 2014
METHODS: UM1 and UM2 oral cancer cells were transfected with siRNA to transketolase (TKT) or siRNA to adenylate kinase (AK2), and Western blotting was used to confirm the knockdown.

New
Oreb et al., Frankfurt am Main, Germany. In Fems Yeast Res, 24 Feb 2014
D-glyceraldehyde-3-phosphate, a glycolytic intermediate, is a substrate of GAPDH but is also utilized by transaldolase and transketolase in the scrambling reactions of the non-oxidative pentose phosphate pathway.
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.

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.
Metabolic flux responses to genetic modification for shikimic acid production by Bacillus subtilis strains.
New
Liu et al., Beijing, China. In Microb Cell Fact, Dec 2013
Experiments on genetic deletion of phosphoenoylpyruvate kinase gene confirmed its positive influence on SA production, while the overexpression of the transketolase gene did not lead to increase in SA production.
[Vitamin B1 (thiamine)].
Review
New
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.
New
Impact
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.
Review
New
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.
Current options and perspectives in the treatment of diabetic neuropathy.
Review
Kempler et al., Szeged, Hungary. In Curr Pharm Des, 2012
The mode of action of benfotiamine is based on inhibition of key alternative pathways, including the polyol, hexosamine, protein-kinase-C pathways, and inhibition of advanced glycation end products formation, just as on activation of transketolase.

Benfotiamine blocks three major pathways of hyperglycemic damage and prevents experimental diabetic retinopathy.
Impact
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.
