l-arabinose uptake studies with Trire2_104072 expressed in yeast. a Comparison of l-arabinose uptake rates of yeast strains transformed with Trire2_104072, XLT1 (Trire2_104072P388H) expression plasmids or with the control plasmid. Significance was estimated with ANOVA and Tukey’s test (**: p < 0.01, ***: p < 0.005). Arabinose concentration was 0.167 mM. Points present results from three individual experiments and bars their average. b Inhibition of l-arabinose transport of Trire2_104072. Arabinose concentration was 0.167 mM and the concentration of the inhibiting sugar was 0.833 mM. Presentation and statistics as in panel a. c Kinetics of l-arabinose uptake of Trire2_104072 at pH 6.5. Points are average values from three independent experiments and the error bars present the standard deviation between them. Line presents the Michaelis–Menten kinetics prediction
