Figure 4.
Specific activities of the sulfation of 4NP by human SULT1A1 allozymes. The concentrations of 4NP used in the enzymatic assays were 0.2 μM (A), 2 μM (B), and 20 μM (C). Data shown represent mean ± standard deviation derived from three determinations. One-way ANOVA was performed in combination with Dunnett’s multiple comparison test (statistically significant from SULTlAl-wild-type: *p<0.05, **p<0.01, ***p<0.001, and ****p<0.0001).
