NCBI Protein Information
Pheophorbide a oxygenase family protein with Rieske 2Fe-2S domain-containing protein
NCBI Summary
Encodes a pheide a oxygenase (PAO). Accelerated cell death (acd1) mutants show rapid, spreading necrotic responses to both virulent and avirulent Pseudomonas syringae pv. maculicola or pv. tomato pathogens and to ethylene.

UniProt Comments
Catalyzes the key reaction of chlorophyll catabolism, porphyrin macrocycle cleavage of pheophorbide a (pheide a) to a primary fluorescent catabolite (pFCC). Works in a two-step reaction with red chlorophyll catabolite reductase (RCCR). Creates the intermediate RCC through the opening of the porphyrin macrocycle by the introduction of one atom of molecular oxygen at the alpha-methine bridge. Seems to be specific for pheide a. Belongs to the chlorophyll catabolic enzymes (CCEs).
