The principal human estrogen, 17 beta-estradiol, is a potent stimulator of certain endocrine-dependent forms of breast cancer. Because human estrogenic 17 beta-hydroxysteroid dehydrogenase (type I 17 beta-HSD) catalyzes the last step in the biosynthesis of 17 beta-estradiol from the less potent estrogen, estrone, it is an attractive target for the design of inhibitors of estrogen production and tumor growth. This human enzyme shares less than 15% sequence identity with a bacterial 3 alpha,20 beta-HSD, for which the three-dimensional structure is known. The amino acid sequence of 17 beta-HSD also differs from that of bacterial 3 alpha,20 beta-HSD by two insertions (of 11 and 14 residues) and 52 additional residues at the C terminus.
