---|---|---|---|
2.4.1.17 | F90A | exhibits little or no activity towards estrone, estradiol and estriol. Complete loss of activity with 2-hydroxyestrone, 2-hydroxyestradiol, 4-hydroxyestradiol and 4-hydroxyestrone | Homo sapiens |
2.4.1.17 | F90L | 86% decrease in activity towards estrone, increase in affinity. Decrease in catalytic activity toward estradiol of 64%, and an almost 3fold increase in affinity. Estriol is not glucuronated by the mutant enzyme. 72% increase in activity towards 2-hydroxyestrone. 78% decrease in activity towards 4-hydroxyestrone. Increase in activity towards 4-hydroxyestradiol | Homo sapiens |
2.4.1.17 | F93A | 75% decrease in activity towards estrone. For estradiol, the F93A mutant showes a slight impairment of activity with 30% decrease in Vmax. The Km for estradiol decreases approximately 2fold. 59% decrease in activity towards estriol, similar KM-value. 99% decrease in activity towards 2-hydroxyestrone. 69% decrease in activity towards 4-hydroxyestrone, increase in affinity. 93% decrease in activity topwards 4-hydroxyestradiol, increase in affinity | Homo sapiens |
2.4.1.17 | F93L | exhibits little or no activity towards estrone, estradiol and estriol. 88% decrease in activity towards 2-hydroxyestrone, increase in affinity. Complete loss in activity towards 4-hydroxyestrone and 4-hydroxyestradiol | Homo sapiens |
