FIGURE 5.
Km values for glucose of the indicated CgHXT proteins. Uptake rates for [14C]glucose yeast cells (strain EBY.VW4000) expressing the respective cDNA were determined at the indicated substrate concentrations at pH 5.0. Insets show double reciprocal (Lineweaver-Burk) plots of the same data (n = 3; ± S.E.).
