Figure 3From: Na+-stimulated phosphate uptake system in Synechocystis sp. PCC 6803 with Pst1 as a main transporterKinetics of phosphate uptake by strains grown in BG-11 (open circles) or Pi-limiting-BG-11 (closed circles) for 24 h: wild type (A), ΔPst1 (B) and ΔPst2 (C). Inset represents a double-reciprocal plot of the concentration dependence of the initial rates of Pi uptake. The units on the X- and Y- axis are μM-1 and (min • mg Chl a) • μmol-1, respectively.Back to article page
