Protein attributes
| Sequence length | 205 AA. |
| Sequence status | Fragment. |
| Protein existence | Evidence at transcript level |
General annotation (Comments)
| Function | Catalyzes the key reaction of chlorophyll catabolism, porphyrin macrocycle cleavage of pheophorbide a (pheide a) to a primary fluorescent catabolite (pFCC). Works in a two-step reaction with pheophorbide a oxygenase (PaO) by reducing the C20/C1 double bond of the intermediate, RCC. |
| Catalytic activity | Primary fluorescent chlorophyll catabolite + NADP+ = red chlorophyll catabolite + NADPH. |
| Pathway | |
| Subunit structure | Homodimer By similarity. |
| Subcellular location | |
| Tissue specificity | In etiolated and green primary leaves. Low amount in roots. |
| Developmental stage | Decreases during leaf senescence, but still present after 8 days of dark-induced senescence. |
| Post-translational modification | The N-terminus is blocked. |
