The enzyme 2-hydroxyisoflavanone dehydratase (EC 4.2.1.105) catalyzes the chemical reaction
- 2,7,4′-trihydroxyisoflavanone daidzein + 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 2,7,4′-trihydroxyisoflavanone hydro-lyase (daidzein-forming). This enzyme is also called 2,7,4′-trihydroxyisoflavanone hydro-lyase. This enzyme participates in isoflavonoid biosynthesis.
The variant GmHID1 from Glycine max converts 2-hydroxyisoflavone to isoflavones, mostly daidzein and genistein. [1]
