Discovery and characterization of pentose-specific transporters in Saccharomyces cerevisiae
… feedstock. Unfortunately, pentose sugars, which make up to 30% of lignocellulose, cannot be utilized by S. cerevisiae. Pentoses can only enter yeast cells through hexose transporters, which have two orders of magnitude lower affinities for pentose sugars. Additionally, inefficient …

Improved xylose fermentation by expression of a putative xylose transporter encoding gene HXT2.4 in Saccharomyces cerevisiae
… S. cerevisiae cannot consume xylose, a pentose sugar which comprises almost 30% of lignocellulosic biomass. Metabolic and genetic engineering methods were used to develop S. cerevisiae that could consume xylose. However in S. cerevisiae, pentose sugars can only enter the cell through native …

Metabolic engineering of Saccharomyces cerevisiae for efficient ethanol production from pentose sugars
… feedstock. Unfortunately, pentose sugars, which constitute up to 30% of biomass hydrolysate, cannot be utilized by S. cerevisiae. To this end, heterologous pentose utilization pathways have been introduced into S. cerevisiae in order to enable the assimilation of pentose sugars. …

Fettsucht mit erhöhter D-Glukose-Absorption im Dünndarm durch Inaktivierung des Regulatorproteins RS1 bei Mäusen
RS1 ist ein 67-68 kD großes, ubiquitär exprimiertes Protein, das sich an der Innenseite der Plasmamembran befindet und in den Zellkern wandern kann. Durch immunhistochemischen Untersuchungen an Dünndarmschnitten der Maus konnte RS1 das erste Mal in dieser Arbeit im Kern und an der Membran von …
