5alpha-hydroxysteroid dehydratase

The enzyme 5α-hydroxysteroid dehydratase catalyzes the chemical reaction


 * 5α-ergosta-7,22-diene-3β,5-diol $$\rightleftharpoons$$ ergosterol + 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 5α-ergosta-7,22-diene-3β,5-diol 5,6-hydro-lyase (ergosterol-forming). This enzyme is also called 5α-ergosta-7,22-diene-3β,5-diol 5,6-hydro-lyase.
