This enzyme belongs to the family of
lyase
In biochemistry, a lyase is an enzyme that catalyzes the breaking (an elimination reaction) of various chemical bonds by means other than hydrolysis (a substitution reaction) and oxidation, often forming a new double bond or a new ring structure. ...
s, 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.
