| 摘要 |
The present invention relates to a polypeptide which has a novel specific arabinose transporter function as well as to nucleic acids coding therefore. The invention further relates to host cells, in particular modified yeast strains which contain the coding nucleic acids and express the polypeptide and functionally integrate it into the plasma membrane and are thus able to absorb L-arabinose. When using modified host cells which express additional proteins of the arabinose metabolic pathway, arabinose can be fermented by these cells, in particular into ethanol. The present invention is therefore relevant, inter alia, in connection with the production of biochemicals from biomass, such as bioethanol for example. |
