title: Dihydrobenzophenanthridine oxidase
text: Dihydrobenzophenanthridine oxidase (DHBP oxidase) is an enzyme.  In the IUBMB Enzyme Nomenclature, dihydrobenzophenanthridine oxidase is .
  
  Dihydrobenzophenanthridine oxidase produces oxidized forms of benzophenanthridine alkaloids:
   In Sanguinaria canadensis (bloodroot), dihydrobenzophenanthridine oxidase produces sanguinarine from dihydrosanguinarine, and chelirubine from dihydrochelirubine.
   In Eschscholzia californica (California poppy), dihydrobenzophenanthridine oxidase produces macarpine from dihydromacarpine.
