Validation of Nrt1p as the main DPI transporter. (a) Growth curves of wild type (ydl227cΔ/ydl227cΔ) and nrt1Δ/nrt1Δ yeast strains in the presence of various DPI concentrations. (b) Comparison of the maximum specific growth rate achieved by the WT strain in the presence of various concentrations of DPI and the competitor nicotinic acid. (c) Comparison of the maximum specific growth rate achieved by the WT strain in the presence of various concentrations of DPI and the competitor thiamine. Error bars = standard error of the mean; n = 3.
