Protoporphyrinogen oxidase (PPO) bụ otu n'ime ebumnuche maka imepụta ụdị ahịhịa ọhụrụ, na-aza ọnụ ahịa dịtụ ukwuu. N'ihi na ogwu ogwu a na-emekarị na chlorophyll ma nwee obere toxicity nye anụ mamma, ahịhịa ahịhịa a nwere njirimara nke arụmọrụ dị elu, obere nsị na nchekwa.
Anụmanụ, osisi, nje bacteria na fungi niile nwere protoporphyrinogen oxidase, nke na-eme ka protoporphyrinogen IX ruo protoporphyrin IX n'okpuru ọnọdụ ikuku oxygen, protoporphyrinogen oxidase bụ enzyme ikpeazụ na-emekarị na tetrapyrrole biosynthesis, nke na-emepụta heme ferrous na chlorophyll. N'ime osisi, protoporphyrinogen oxidase nwere isoenzymes abụọ, nke dị na mitochondria na chloroplasts n'otu n'otu. Protoporphyrinogen oxidase inhibitors bụ ike kọntaktị herbicides, nke nwere ike nweta nzube nke igbo akara tumadi site inhibiting njikọ nke osisi pigmenti, na nwere obere oge fọdụrụnụ na ala, nke na-adịghị emerụ na-emecha kụrụ.
