Concentration dependence of arginine XAR. Wild-type cells were assayed for survival efficiency or the arginine-agmatine exchange rate. (A) For survival data, the solid curve is calculated with the Hill equation, with a half-maximal concentration of 100 μM and a slope factor of 3.2. (B) Initial transport rate data follow a Michaelis-Menten curve, with a half-maximal concentration of 83 μM. These curves are purely empirical and have no theoretical connotations.
