Figure 3. Urate and fructose transport mediated by WT hSLC2A9 and its Y298Q and N429H mutants.

Figure 3

Panel (A) Michaelis-Menten curves of 14C urate kinetics of hSLC2A9 WT (▪), Y298Q (○) and N429H (Δ). Panel (B) 14C urate kinetic constants and the standard error of the regression (Sy. X) of the three isoforms (n ≥ 3). Panel (C) Michaelis-Menten curves of urate-induced currents of WT hSLC2A9, Y298Q and N429H mutants. Panel (D) Urate-induced current kinetic constants and the standard error of the regression (Sy. X) of the WT and two mutants (n ≥ 15 oocytes from 3 frogs). Panel (E) Current-voltage curve of 1 mM urate-induced current obtained using a RAMP protocol WT hSLC2A9 (▪), Y298Q (○) and N429H (Δ) mutant expressing oocytes. (n ≥ 15 oocytes from 3 frogs). Panel (F) 14C fructose uptake mediated by WT hSLC2A9 and its mutants. (n ≥ 3, One-way ANOVA, *p < 0.05).
