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