Comments "The Km values of glucose uptake in S. pombe wild-type cells were determined to be about 1–6 mM [primary sources 5, 162, 163] which is in the range of high-affinity facilitated diffusion systems. In contrast, proton glucose symport systems of other yeasts exhibit considerably lower Km values [primary source 5]."
