Pheophorbide a oxygenase
Template:Short description Template:Infobox enzyme Pheophorbide a oxygenase (Template:EC number, 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]
