ENZYME entry: EC

Accepted Name
red chlorophyll catabolite reductase
Alternative Name(s)
RCC reductase
red Chl catabolite reductase
Reaction catalysed
2 oxidized [2Fe-2S]-[ferredoxin] + primary fluorescent chlorophyll catabolite = 3 H(+) + red chlorophyll catabolite + 2 reduced [2Fe-2S]-[ferredoxin]
  • The enzyme participates in chlorophyll degradation, which occurs during leaf senescence and fruit ripening in higher plants.
  • The reaction requires reduced ferredoxin, which is generated from NADPH produced either through the pentose-phosphate pathway or by the action of photosystem I.
  • This reaction takes place while red chlorophyll catabolite is still bound to EC
  • 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 environment causes their non-enzymic conversion into colorless breakdown products called non-fluorescent chlorophyll catabolites (NCCs).
  • Formerly EC
