== Function ==
[https://www.uniprot.org/uniprot/DHB14_HUMAN DHB14_HUMAN] Has NAD-dependent 17-beta-hydroxysteroid dehydrogenase activity. Converts oestradiol to oestrone. The physiological substrate is not known. Acts on oestradiol and 5-androstene-3-beta,17-beta-diol (in vitro).<ref>PMID:17067289</ref>

== Publication Abstract from PubMed ==
17beta-HSD14 is a SDR enzyme able to oxidize estradiol and 5-androstenediol using NAD+. We determined the crystal structure of this human enzyme as the holo form and as ternary complexes with estrone and with the first potent, nonsteroidal inhibitor. The structures reveal a conical, rather large and lipophilic binding site and are the starting point for structure-based inhibitor design. The two natural variants (S205 and T205) were characterized and adopt a similar structure.
