Alignment of Hxt1, Hxt36, and Hxt5 transporters. The lysine residues mutated in the respective hexose transporters are boxed, and the transmembrane domains (TMDs) are shaded gray. The position of the asparagine residue in Hxt36 that was mutated to an alanine to obtain Hxt36-N367A mutant is indicated with an arrow. Numbering of the targeted lysine residues is for Hxt36
