The enzyme protoaphin-aglucone dehydratase (cyclizing) (EC 4.2.1.73) catalyzes the chemical reaction
- protoaphin aglucone xanthoaphin + 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 protoaphin-aglucone hydro-lyase (cyclizing; xanthoaphin-forming). Other names in common use include protoaphin dehydratase, protoaphin dehydratase (cyclizing), and protoaphin-aglucone hydro-lyase (cyclizing).
