Polyphenol Oxidase [PPO]

Polyphenol oxidase is the biocatalyst of tea polyphenol and is able to catalyze redox reactions to form quinone as final product. The reaction is chromogenic and is widely observed in plants such as apple, litchi, potato and spinach. Part BBa_K3091000's sequence comes from PPO found in potato.
