NOVELTY - A recombinant xylose transporter protein comprising transporter motif sequence corresponding to amino acid residue positions 36, 37, 38, 39, 40, and 41 of Candida intermedia strain GXS1 protein, is new. The transporter motif sequence is -Gly-Gly/Phe-X1-X2-X3-Gly-(I).    USE - The recombinant xylose transporter protein is useful for transporting xylose into yeast cell for converting xylose to biofuel (all claimed).    DETAILED DESCRIPTION - A recombinant xylose transporter protein comprising transporter motif sequence corresponding to amino acid residue positions 36, 37, 38, 39, 40, and 41 of Candida intermedia strain GXS1 protein, is new. The transporter motif sequence is -Gly-Gly/Phe-X1-X2-X3-Gly-(I). The transporter motif sequence is not -Gly-Gly-Leu-Ile-Phe-Gly- or -Gly-Gly-Phe-Ile-Phe-Gly-.    X1=Asp, Cys, Gly, His, Ile, Leu, or Phe;    X2=Ala, Asp, Cys, Glu, Gly, His, or Ile;and    X3=Asn, Cys, Gln, Phe, Gly, Leu, Met, Ser, Thr, or Pro.    INDEPENDENT CLAIMS are included for the following: (1) yeast cell comprising the recombinant xylose transporter protein, or recombinant galactose-arabinose transporter protein; (2) recombinant galactose-arabinose transporter protein comprising transporter motif sequence corresponding to amino acid residue positions 36, 37, 38, 39, 40, and 41 of C.intermedia strain GXS1 protein, where the transporter motif sequence is -Gly-Gly/Phe-X4-X5-X6-Gly- of formula (II), and the sequence is not -Gly-Gly-Leu-Val-Tyr-Gly-, or -Gly-Gly-Phe-Val-Phe-Gly-; (3) nucleic acid encoding the above-mentioned recombinant xylose transporter protein, or recombinant galactose-arabinose transporter protein; (4) method (M1) for transporting xylose into yeast cell, involves (i) contacting yeast cell comprising the recombinant xylose transporter protein of with a xylose compound, and (ii) allowing the recombinant xylose transporter protein to transport the xylose compound into the yeast cell; (5) method (M2) for transporting galactose or arabinose into yeast cell, involves (a) contacting yeast cell comprising the recombinant galactose-arabinose transporter protein with galactose compound or an arabinose compound, and (b) allowing the recombinant galactose-arabinose transporter protein to transport the galactose compound or the arabinose compound into the yeast cell.    X4=Phe or Thr;    X5=Pro or Ile;and    X6=Met or Thr.
