Figure 1. GSSG inactivation of human SULTs in human liver cytosol.

Figure 1

Human liver cytosol (from a 15-year-old male) was treated with the indicated concentrations of GSSG for 20 min at room temperature. Then enzyme activities against [14C]2-naphthol (hSULT1A1 and hSULT1A3), [3H]estradiol (hSULT1E1), and [3H]DHEA (hSULT2A1) were determined [21, 22]. Relative (%) activities to controls are plotted as a function of GSSG concentration.
