Kinetic parameters of the human STSa
| Vmax (pmol/min/mg) | Km (μM) | Vmax/Km | |
|---|---|---|---|
| Cho-sulfate | 998.7 ± 44.8 | 5.73 ± 0.84 | 174.4 |
| DHEA-sulfate | 883.1 ± 14.1 | 2.85 ± 0.23 | 310.0 |
| E1-sulfate | 5538.0 ± 193.8 | 5.05 ± 0.39 | 1095.8 |
| E2-sulfate | 5715.0 ± 280.6 | 4.31 ± 0.47 | 1326.0 |
| Preg-sulfate | 1188.0 ± 14.8 | 1.75 ± 0.04 | 680.4 |
Results represent means ± SD derived from three determinations.
Kinetic parameters were determined based on the equation for Michaelis-Menten kinetics.
