Abstract
Official abstract text for this publication.
The present disclosure relates to host cells containing a recombinant polynucleotide encoding a polypeptide where the polypeptide transports cellodextrin into the cell. The present disclosure further relates to methods of increasing transport of cellodextrin into a cell, methods of increasing growth of a cell on a medium containing cellodextrin, methods of co-fermenting cellulose-derived and hemicellulose-derived sugars, and methods of making hydrocarbons or hydrocarbon derivatives by providing a host cell containing a recombinant polynucleotide encoding a polypeptide where the polypeptide transports cellodextrin into the cell. The present disclosure relates to host cells containing a recombinant polynucleotide encoding a polypeptide where the polypeptide transports a pentose into the cell, methods of increasing transport of a pentose into a cell, methods of increasing growth of a cell on a medium containing pentose sugars, and methods of making hydrocarbons or hydrocarbon derivatives by providing a host cell containing a recombinant polynucleotide encoding a polypeptide where the polypeptide transports a pentose into the cell.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method of increasing transport of cellodextrin into a cell, comprising: culturing a host cell which comprises a recombinant polynucleotide encoding a cellodextrin transporter polypeptide in a medium such that the recombinant polynucleotide is expressed, said cellodextrin transporter having the structure of a Major Facilitator Superfamily protein and comprising transmembrane α-helix 1, α-helix 2, α-helix 3, α-helix 4, α-helix 5, α-helix 6, α-helix 7,…
