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 + NADPH + H+ + O2 red chlorophyll catabolite + NADP+
Pheophorbide a oxygenase participates in chlorophyll degradation. Loss-of-function mutations in the gene can lead to a stay-green phenotype in plants. [7]
