Pheophytin pheophorbide hydrolase (pheophytinase) is involved in chlorophyll breakdown during leaf senescence. Chlorophyllase (the other first step chrorophylle degrading enzyme) is not localized to plastids, and double knockout mutant plants still are able to degrade chlorophyll during leaf senescence. So pheophytinase is a new pathway. This entry represents a group of pheophytinases from plants, including PPH, a chloroplast-located and senescence-induced hydrolase widely distributed in algae and land plants. In Arabidopsis, PPH (also known as CRN1) specifically dephytylates the Mg-free chlorophyll pigment, pheophytin (phein), yielding pheophorbide. It plays a crucial role in Chlorophyll degradation during leaf senescence
