Pheophorbidase
Template:Infobox enzyme Pheophorbidase (EC 3.1.1.82, phedase, PPD) is an enzyme with systematic name pheophorbide-a hydrolase.[1][2][3] It catalyses the following 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.
