pheophorbidase
Cat No.
EXWM-3511
Description
This enzyme forms part of the chlorophyll degradation pathway, and is found in higher plants and in algae. In higher plants it participates in de-greening processes such as fruit ripening, leaf senescence, and flowering. The enzyme exists in two forms: type 1 is induced by senescence whereas type 2 is constitutively expressed. The enzyme is highly specific for pheophorbide as substrate (with a preference for pheophorbide a over pheophorbide b) as other chlorophyll derivatives such as protochlorophyllide a, pheophytin a and c, chlorophyll a and b, and chlorophyllide a cannot act as substrates. Another enzyme, called pheophorbide demethoxycarbonylase (PDC),produces pyropheophorbide a from pheophorbide a without forming an intermediate although the precise reaction is not yet known.
Form
Liquid or lyophilized powder
Enzyme Commission Number
Storage
Store it at +4 ºC for short term. For long term storage, store it at -20 ºC～-80 ºC.
Synonyms
phedase; PPD
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)
