Xylose transport in the human jejunum

Digestive Diseases and Sciences, 1989
D-Xylose transport in the human jejunum was studied in vivo using a standard intestinal perfusion technique, and also in vitro in human jejunal brush border membrane vesicles. Initial D-xylose concentrations were linearly related to D-xylose absorption rates, a finding consistent with passive diffusion.

Xylose transport pathways in rabbit ileum

American Journal of Physiology-Gastrointestinal and Liver Physiology, 1980
The D-xylose transepithelial transport mechanism was examined in rabbit ileum in vitro. The net flux of D-xylose (Jxylnet) from mucosa to serosa is abolished in the presence of 10(-4) M ouabain. D-Xylose stimulates the net flux of sodium (JNanet) and the short-circuit current (Isc) equally.

Control of xylose consumption by xylose transport in recombinant Saccharomyces cerevisiae

Biotechnology and Bioengineering, 2003
AbstractSaccharomyces cerevisiae TMB3001 has previously been engineered to utilize xylose by integrating the genes coding for xylose reductase (XR) and xylitol dehydrogenase (XDH) and overexpressing the native xylulokinase (XK) gene. The resulting strain is able to metabolize xylose, but its xylose utilization rate is low compared to that of natural ...

Expression of a heterologous xylose transporter in a Saccharomyces cerevisiae strain engineered to utilize xylose improves aerobic xylose consumption

Applied Microbiology and Biotechnology, 2008
The goal of this investigation was to determine the effect of a xylose transport system on glucose and xylose co-consumption as well as total xylose consumption in Saccharomyces cerevisiae. We expressed two heterologous transporters from Arabidopsis thaliana in recombinant xylose-utilizing S. cerevisiae cells.

Transport of xylose and glucose in the xylose-fermenting yeast Pichia stipitis

Applied Microbiology and Biotechnology, 1988
A low-affinity and a high-affinity sylose proton symport operated simultaneously in both starved and non-starved cells of Pichia stipitis. Glucose competed with xylose for transport by the low-affinity system and inhibited xylose transport by the high-affinity system non-competitively.

Directed evolution of xylose specific transporters to facilitate glucose‐xylose co‐utilization

Biotechnology and Bioengineering, 2015
ABSTRACTA highly active xylose specific transporter without glucose inhibition is highly desirable in cost‐effective production of biofuels from lignocellulosic biomass. However, currently available xylose specific transporters suffer from low overall activity and most are inhibited by glucose. In this study, we applied a directed evolution strategy to
