Journal ArticleDOI
De novo biosynthesis of vanillin in fission yeast (Schizosaccharomyces pombe) and baker's yeast (Saccharomyces cerevisiae).
Esben Halkjaer Hansen,Birger Lindberg Møller,Gertrud R. Kock,Camilla M. Bünner,Charlotte Kristensen,Ole R. Jensen,Finn Thyge Okkels,Carl Erik Olsen,Mohammed Saddik Motawia,Jørgen Hansen +9 more
TL;DR: These de novo pathways represent the first examples of one-cell microbial generation of these valuable compounds from glucose in S. pombe yeast and baker's yeast, as well as in Saccharomyces cerevisiae, which have not previously been metabolically engineered to produce any valuable, industrially scalable, white biotech commodity.
Journal ArticleDOI
Metabolic engineering of dhurrin in transgenic Arabidopsis plants with marginal inadvertent effects on the metabolome and transcriptome
Charlotte Kristensen,Marc Morant,Carl Erik Olsen,Claus Thorn Ekstrøm,David W. Galbraith,Birger Lindberg Møller,Søren Bak +6 more
TL;DR: Results demonstrate that insertion of high-flux pathways directing synthesis and intracellular storage of high amounts of a cyanogenic glucoside or a glucosinolate is achievable in transgenic A. thaliana plants with marginal inadvertent effects on the transcriptome and metabolome.
Journal ArticleDOI
The in vitro substrate regiospecificity of recombinant UGT85B1, the cyanohydrin glucosyltransferase from Sorghum bicolor
Karina Sinding Hansen,Charlotte Kristensen,David B. Tattersall,Patrik R. Jones,Carl Erik Olsen,Søren Bak,Birger Lindberg Møller +6 more
TL;DR: UGT85B1 has a rather broad substrate specificity in vitro but shows regiospecificity, demanding the presence of a sterically unhindered hydroxyl group e.g. as part of a cyanohydrin function, as a primary alcohol or as a phenolic hydroxy group.
Journal ArticleDOI
Substrate specificities of family 1 UGTs gained by domain swapping
Esben Halkjaer Hansen,Sarah A. Osmani,Charlotte Kristensen,Birger Lindberg Møller,Jørgen Hansen +4 more
TL;DR: It is demonstrated that it is possible to obtain improved catalytic properties by combining domains from both closely as well as more distantly related glycosyltransferases to gain improved substrate specificity and catalytic efficiency.
Journal ArticleDOI
Spot shape modelling and data transformations for microarrays
TL;DR: A substantial improvement is obtained for the dataset studied by the polynomial-hyperbolic spot shape model in combination with the Box-Cox transformation and the spatial statistical models are used to correct spot measurements with saturation by extrapolating the censored data.
