1.1.1.62 | 4-androstene-3,17-dione + NADPH + H+ |
17beta-HSD3 and 5, formation of active androgens in testis and prostate |
1.1.1.62 | 4-estrene-3,17-dione + NADPH |
- |
1.1.1.62 | 5alpha-androstane-3alpha,17beta-diol + NAD+ |
- |
1.1.1.62 | 5alpha-dihydrotestosterone + NADP+ |
the enzyme could play a critical role in estrogen-sensitive cells, since it inactivates 5alpha-dihydrotestosterone that generally shows antagonistic effect in the cells |
1.1.1.62 | androstenedione + NAD(P)H + H+ |
- |
1.1.1.62 | estradiol-17beta + NAD(P)+ |
17beta-HSD2 and 5, key role in regulating steroid receptor occupancy in normal and tumor tissues |
1.1.1.62 | estradiol-17beta + NAD(P)+ |
17beta-HSD4 is involved in etsrogen inactivation and may protect against an excessive accumulation of E2 in human ovarian epithelial cells |
