Fig. 2From: Identification and functional characterization of a novel arginine/ornithine transporter, a member of a cationic amino acid transporter subfamily in the Trypanosoma cruzi genomeSubstrate saturation curves for [3H]-arginine and [14C]-ornithine in the Saccharomyces cerevisiae expression system. a and b are time course curves in (●) galactose-induced and (○) glucose-repressed yeast cells. c and d depict the concentration dependence of the [3H]-arginine and [14C]-ornithine uptake rates in linear ranges. Data from control assays with glucose-repressed cells were subtracted from those from assays with galactose-induced cells, and a Lineweaver-Burk plot of the data is shown in the inset. The results are presented as the mean ± SD of one experiment performed in triplicateBack to article page
