DE   Red chlorophyll catabolite reductase.
AN   RCC reductase.
AN   RCCR.
AN   Red Chl catabolite reductase.
CA   Primary fluorescent chlorophyll catabolite + NADP(+) = red chlorophyll
CA   catabolite + NADPH.
CC   -!- Chlorophyll degradation is a characteristic symptom of leaf
CC       senescence and fruit ripening.
CC   -!- The reaction catalyzed by this enzyme requires reduced ferredoxin,
CC       which is generated either by NADPH through the pentose-phosphate
CC       pathway or by the action of photosystem I.
CC   -!- This reaction takes place without release of the substrate from
CC       EC 1.14.12.20.
CC   -!- Depending on the plant species used as the source of enzyme, one of
CC       two possible C-1 epimers of primary fluorescent chlorophyll
CC       catabolite (pFCC), pFCC-1 or pFCC-2, is normally formed, with all
CC       genera or species within a family producing the same isomer.
CC   -!- After modification and export, pFCCs are eventually imported into the
CC       vacuole, where the acidic envirionment causes their non-enzymic
CC       conversion into colorless breakdown products called non-fluorescent
CC       chlorophyll catabolites (NCCs).
