Conservation of motifs and residues reported to be relevant for xylose transport. A multiple sequence alignment of known xylose transporters, including A. niger XltA-C and T. reesei Str1-3 was constructed using the EMBL-EBI Clustal Omega tool [68]. Reported relevant motifs and residues are in bold; amino acids highlighted in blue indicate the transporter where motifs/residues were described to be relevant for xylose transport
