Comments
This enzyme belongs to the short-chain dehydrogenase/reductase (SDR) superfamily, along with Drosophia alcohol dehydrogenase (S00319 in EzCatDB). This enzyme has got a catalytic triad composed of conserved residues, Ser, Tyr, and Lys. The conformation of these residues, compared to that of the NAD molecule, seems to be similar to that of the homologous enzymes. Thus, its catalytic mechanism must be similar to those of the homologous enzymes.
According to the literature [37], type 1 of this enzyme (17-beta-hydroxysteroid dehydrogenase) (Swiss-prot;P14061) catalyzes the reduction of estrone to estradiol-17-beta, whereas type 11 (Swiss-prot;Q8NBQ5) catalyzes the oxidation/dehydrogenation of 5-alpha-androstanediol to androstrone.
