d-Xylose uptake by the in vivo engineered S. cerevisiae strain. Uptake of 100 mM d-[14C]xylose by the DS69473 (□) and DS69473Evo (■) strains in the presence of competing concentrations of d-glucose ranging from 0 to 800 mM. (inset) Xylose uptake normalized to the rate observed in the absence of competing glucose.
