MeSH definition : A membrane-bound flavoenzyme that catalyzes the oxygen-dependent aromatization of
protoporphyrinogen IX (Protogen) to protoporphyrin IX (Proto IX). It is the last enzyme
of the common branch of the HEME and CHLOROPHYLL pathways in plants, and is the molecular
target of diphenyl ether-type herbicides. VARIEGATE PORPHYRIA is an autosomal dominant
disorder associated with deficiency of protoporphyrinogen oxidase.;
