Specific activities of the sulfation of dopamine (DA) by human SULT1A3 allozymes. Concentrations of dopamine used in the enzymatic assays were 0.5 μM (A) and 5.0 μM (B). Specific activity refers to nmol dopamine sulfated/min/mg of purified allozyme. Data shown represent mean ± standard deviation derived from three determinations. WT refers to wild-type SULT1A3.
