HUMAN ESTROGENIC 17BETA-HYDROXYSTEROID DEHYDROGENASE
Overview
BACKGROUND: 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. RESULTS: The 2.20 A resolution, ... [(full description)]
