metabolism | The key step in Chl breakdown in green plants, the cleavage reaction of the porphinoid macrocycle, is catalyzed by an oxygenase that specifically recognizes pheophorbide a (Pheide a). The conversion of Pheide a to a primary blue fluorescent catabolite (pFCC) requires the joint action of PaO and the soluble stroma-located enzyme RCC reductase that reduces the intermediary red catabolite (RCC) to pFCC, structures of breakdown products of chlorophyll, overview | Brassica napus |
physiological function | the conversion of Pheide a to a primary blue fluorescent catabolite (pFCC) requires the joint action of PaO and a soluble stroma-located enzyme that reduces an intermediary red catabolite (RCC) to pFCC. Both PaO and RCC reductase require reduced ferredoxin as reductant. Although RCC reductase is present at all stages of development and in all tissues examined, PaO seems to occur in gerontoplasts exclusively | Brassica napus |
