Pheophorbide a oxygenase (EC 1.14.15.17, pheide a monooxygenase, pheide a oxygenase, PAO) is an enzyme with systematic name pheophorbide-a,NADPH:oxygen oxidoreductase (biladiene-forming).
[1][2][3][4][5][6] This enzyme catalyses the following chemical reaction Pheophorbide a oxygenase participates in chlorophyll degradation.
Loss-of-function mutations in the gene can lead to a stay-green phenotype in plants.
