| Type: | Domain | Name: | Protoporphyrinogen oxidase, C-terminal domain |
| Description: | This entry represents the C-terminal domain of protoporphyrinogen oxidase (PPO). Mitochondrial PPO2 has been shown to consist of three domains: a FAD-binding, a substrate-binding and a membrane-binding domain []. Protoporphyrinogen oxidase () oxidises protoporphyrinogen IX to protoporphyrin IX, a precursor of haem and chlorophyll, in the penultimate step in haem and porphyrin biosynthesis. Bacillus subtilisHemY also has coproporphyrinogen III to coproporphyrin III oxidase activity in a heterologous expression system, although the role for this activity in vivois unclear. | Short Name: | PPOX_C |
