Protein attributes
| Sequence length | 537 AA. |
| Sequence status | Complete. |
| Sequence processing | The displayed sequence is further processed into a mature form. |
| Protein existence | Evidence at transcript level |
General annotation (Comments)
| Function | Catalyzes the 6-electron oxidation of protoporphyrinogen-IX to form protoporphyrin-IX. |
| Catalytic activity | Protoporphyrinogen-IX + 3 O2 = protoporphyrin-IX + 3 H2O2. |
| Cofactor | FAD By similarity. |
| Pathway | |
| Subcellular location | Plastid › chloroplast Potential. |
| Tissue specificity | Expressed at high levels in the leaves and at low levels in the roots and floral buds. |
| Sequence similarities | Belongs to the protoporphyrinogen oxidase family. |
| Sequence caution | The sequence AAC72870.1 differs from that shown. Reason: Erroneous gene model prediction. |
