Pheophorbidase (EC 3.1.1.82, phedase, PPD) is an enzyme with systematic name pheophorbide-a hydrolase. This enzyme catalyses the following chemical reaction

pheophorbide a + H₂O ⇌ pyropheophorbide a + methanol + CO₂ (overall reaction)(1a) pheophorbide a + H₂O ⇌ C-132-carboxypyropheophorbide a + methanol(1b) C-132-carboxypyropheophorbide a ⇌ pyropheophorbide a + CO₂ (spontaneous)

This enzyme participates in the chlorophyll degradation in higher plants and algae.
