metabolism | the enzyme is involved in the chlorophyll metabolism. Chlorophyllide is not a first intermediate of chlorophyll breakdown, almost unchanged chlorophyll to chlorophyllide ratio after 24 h of paraquat treatment. Melatonin treatment of seeds enhances the ability of pea seedlings to accelerate chlorophyll breakdown and chlorophyll de novo synthesis before oxidative stress exerted by herbicide paraquat treatment appears and several hours after stressing, respectively, while during prolonged paraquat incubation, melatonin delays chlorophyll degradation | Pisum sativum |
physiological function | chlorophyll (Chl) breakdown, Chl degradation into phytol, is a multistep enzymatic process, phytol is the first decomposition product of the porphyrin ring. The breakdown takes place in four successive steps catalyzed by chlorophyllase (Chlase), Mg-dechelatase, PAO and red chlorophyll catabolite reductase. Enzyme chlorophyllase (Chlase) catalyzes the reaction of chlorophyll hydrolysis to chlorophyllide (Chlide) and phytol, and it is the first enzyme of Chl catabolism during fruit ripening and leaf senescence | Pisum sativum |
