Comparison of heterologous xylose transporters in recombinant
Background Baker's yeast (Saccharomyces cerevisiae) has been engineered for xylose utilization to enable production of fuel ethanol from lignocellulose raw material. One unresolved challenge is that S.

Engineering of an endogenous hexose transporter into a specific D-xylose transporter facilitates glucose-xylose co-consumption in Saccharomyces cerevisiae. [PDF]
Engineering of Saccharomyces cerevisiae for the simultaneous utilization of hexose and pentose sugars is vital for cost-efficient cellulosic bioethanol production. This yeast lacks specific pentose transporters and depends on endogenous hexose transporters for low affinity pentose uptake.

An evolved xylose transporter from
Background Xylose is a second most abundant sugar component of lignocellulose besides glucose. Efficient fermentation of xylose is important for the economics of biomass-based biorefineries.

Characterization of the xylose-transporting properties of yeast hexose transporters and their influence on xylose utilization [PDF]
For an economically feasible production of ethanol from plant biomass by microbial cells, the fermentation of xylose is important. As xylose uptake might be a limiting step for xylose fermentation by recombinant xylose-utilizing Saccharomyces cerevisiae cells a study of xylose uptake was performed.

Proton-linked D-xylose transport in Escherichia coli [PDF]
The addition of xylose to energy-depleted cells of Escherichia coli elicited an alkaline pH change which failed to appear in the presence of uncoupling agents. Accumulation of [14C]xylose by energy-replete cells was also inhibited by uncoupling agents, but not by fluoride or arsenate. Subcellular vesicles of E.

Utilization of d-ribose through d-xylose transporter [PDF]
An Escherichia coli mutant defective in high-affinity D-ribose transport is able to utilize the sugar as a sole carbon source, suggesting that other transport systems for D-ribose exist. In order to search for such transporters, transposon mutagenesis was carried out in an rbsB-negative strain containing ribokinase (rbsK) for sugar phosphorylation ...

XylE is a bacterial xylose transporter and homologue of human glucose transporters GLUTs 1-4. HDX-MS, mutagenesis and MD simulations suggest that protonation of a conserved aspartate triggers conformational transition from outward- to inward facing state

Engineering of Pentose Transport in Saccharomyces cerevisiae for Biotechnological Applications
Lignocellulosic biomass yields after hydrolysis, besides the hexose D-glucose, D-xylose, and L-arabinose as main pentose sugars. In second generation bioethanol production utilizing the yeast Saccharomyces cerevisiae, it is critical that all three sugars

Intestinal Transport of D-Xylose.
SummaryThe intestinal transport of D-Xylose was studied in the rat using 2 different methods of in situ perfusion. The absorption of xylose is inhibited by the presence in the perfusate of any of the following substances (listed in decreasing order of their inhibitory ability): phlorizin > glucose > 3-0-methylglucose > fructose > 3-0-methyl-fructose ...

Background Glucose repression in yeast leads to the sequential or diauxic utilization of mixed sugars and reduces the co-utilization of glucose and xylose from lignocellulosic biomasses.
