"The Regulation of Pheophorbide a Oxygenase (Pao) in the ""Green Seed"" Problem in Canola and During Leaf Senescence"
… by freezing conditions have been identified. Pheophorbide a oxygenase (PaO) is considered to be a key enzyme in regulating chlorophyll degradation. Pheophorbide a, the substrate of PaO, and other chlorophyll catabolites from canola seeds accumulated after exposure to freezing conditions. …

Evidence for reversible phosphorylation as a post-translational regulatory mechanism in the chlorophyll catabolic pathway
… governing activity of one enzyme in particular, pheophorbide a oxygenase (PaO), is especially desirable as PaO catalyzes the oxidative opening of the porphyrin ring structure, considered to be the key regulatory point in chlorophyll degradation. Through site-directed mutagenesis of the …

Computational analysis of upstream regulatory elements regulating plant chlorophyll degradation
… degradation pathway involves the enzyme pheophorbide a oxygenase (PAO), which oxidizes the chlorophyll degradation intermediate pheide a, that is eventually converted to non-fluorescent chlorophyll catabolites (NCCs). PAO activation in maturing green seeds is known to be disrupted …
