In enzymology, a 5alpha-hydroxysteroid dehydratase (EC 4.2.1.62) is an enzyme that catalyzes the chemical reaction
- 5alpha-ergosta-7,22-diene-3beta,5-diol
ergosterol + H2O
Hence, this enzyme has one substrate, 5alpha-ergosta-7,22-diene-3beta,5-diol, and two products, ergosterol and H2O.
This enzyme belongs to the family of lyases, specifically the hydro-lyases, which cleave carbon-oxygen bonds. The systematic name of this enzyme class is 5alpha-ergosta-7,22-diene-3beta,5-diol 5,6-hydro-lyase (ergosterol-forming). This enzyme is also called 5alpha-ergosta-7,22-diene-3beta,5-diol 5,6-hydro-lyase.
