FIG. 1.

Inhibition of maltose transport by trehalose. Rates of zero-trans uptake of maltose were measured at 5 mM [¹⁴C]maltose in the presence of the indicated concentrations of trehalose. For each strain, the rate in the absence of trehalose was set at 1.00. The figure shows the reciprocal rates (1/V) plotted against trehalose concentration for two ale yeasts, A60 (×) and A179 (•) and three lager yeasts: A15 (⧫), A24 (▪), and A64 (▴). Error bars show the range between two or three independent experiments.
