Production of cinnamic and p -hydroxycinnamic acid from sugar mixtures with engineered Escherichia coli.
In Microb Cell Fact, 16 Feb 2015
However, sustainable production processes should preferably be based on the use of waste material such as lignocellulosic hydrolysates.ResultsIn this study, E. coli strains with active (W3110) and inactive phosphoenolpyruvate:sugar phosphotransferase system (PTS) (VH33) were engineered for CA and pHCA production by transforming them with plasmids expressing genes encoding phenylalanine/tyrosine ammonia lyase (PAL/TAL) enzymes from Rhodotorula glutinis or Arabidopsis thaliana as well as genes aroG fbr and tktA, encoding a feedback inhibition resistant version of 3-deoxy-D-arabino-heptulosonate 7-phosphate synthase and transketolase, respectively.
Structure and functioning mechanism of transketolase.
Moscow, Russia. In Biochim Biophys Acta, Sep 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 .
Engineering stereoselectivity of ThDP-dependent enzymes.
London, United Kingdom. In Febs J, 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.
[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.
The role of thiamine in cancer: possible genetic and cellular signaling mechanisms.
Westminster, United States. In Cancer Genomics Proteomics, 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.
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.
