Abstract
The invention relates to a variant of a parent polypeptide which is preferably a hexose transporter, wherein the variant comprises an amino acid sequence which, when aligned with the amino acid sequence of SEQ ID NO: 1, comprises a substitution of amino acids N376 and T89, the positions of said amino acids being defined with reference to the amino acid sequence of SEQ ID NO: 1. Said polypeptide is suitable in the production of ethanol from arabinose-rich biomass such as corn stover and corn starch.
