General annotation (Comments)

Function

Catalyzes the key reaction of chlorophyll catabolism, porphyrin macrocycle cleavage of pheophorbide a (pheide a) to a primary fluorescent catabolite (pFCC). Works in a two-step reaction with pheophorbide a oxygenase (PaO) by reducing the C20/C1 double bond of the intermediate, RCC.

Catalytic activity

Primary fluorescent chlorophyll catabolite + NADP+ = red chlorophyll catabolite + NADPH.

Pathway

Porphyrin degradation; chlorophyll degradation.

Subunit structure

Homodimer Probable.

Subcellular location

Plastidchloroplast stroma.

Tissue specificity

In etiolated and green primary leaves. Low amount in roots.

Developmental stage

Decreases during leaf senescence, but still present after 8 days of dark-induced senescence.

Post-translational modification

The N-terminus is blocked.
