Title:
PENTOSE TRANSPORTER
Document Type and Number:
WIPO Patent Application WO/2011/027796
Kind Code:
A1
Abstract:
Useful substances such as bioethanol can be produced from pentoses utilizing biomass resources effectively.
Disclosed are: use of HGT2 gene or an expression product protein thereof as a xylose transporter; a xylose and/or L-arabinose transporter comprising an expression product protein of a gene selected from the group consisting of HGT2 gene, XUT1 gene and HXT2.4 gene; use of a gene selected from the group consisting of HGT2 gene, XUT1 gene and HXT2.4 gene as a xylose and/or L-arabinose transporter; and a method for producing bioethanol, which is characterized by introducing at least one gene selected from the group consisting of HGT2 gene, XUT1 gene and HXT2.4 gene into yeast and culturing the yeast in the presence of a biomass containing xylose and/or L-arabinose.
