| evolution | red chlorophyll catabolite reductases appear to represent a phylogenetically early addition to the chlorophyll catabolic pathway. Two types of red chlorophyll-catabolite reductases (RCCR), named RCCR-type 1 and RCCR-type 2, appear to have evolved in higher plants. Chlorophyll catabolism in higher plants differs remarkably from that in the green alga by the formation of FCCs and NCCs | Capsicum annuum |

| metabolism | in chlorophyll breakdown, the conversion of pheophorbide a to primary fluorescent chlorophyll catabolites is catalyzed by the joint action of the two enzymes PaO, a membrane-bound enzyme, and the soluble stroma enzyme RCCR. The former cleaves the porphyrin macrocycle oxidatively and produces a bound form of the intermediary catabolite (RCC), which seems to be reduced stereoselectively on the C20=C1 bond by the action of the reductase | Capsicum annuum |

| additional information | the primary fluorescent chlorophyll catabolite Ca-FCC-2 from sweet pepper, Capsicum annuum, chromoplasts has similar optical properties, but is slightly less polar than the primary FCC from senescent cotyledons of oilseed rape, Brassica napus, determination of structure and constitution by fast-atom-bombardment mass spectra and homo- and heteronuclear magnetic resonance experiments. Two-dimensional homonuclear spectra of Ca-FCC-2 reveals it to differ from pFCC by the configuration at the methine atom C1, whose configuration results from the action of red chlorophyll catabolite reductase, RCCR. Structure analysis, overview | Capsicum annuum |
