Pheophorbidase

Pheophorbidase (EC 3.1.1.82, phedase, PPD) is an enzyme with systematic name pheophorbide-a hydrolase.[1][2][3] 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)
