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.

<p>We built this new part as an approach to detecting bacteriophages in fecal polluted water through color change. This enzyme is from Solanum tuberosum, and would cause yellow solution containing tea polyphenol turn red. Also, the product of the reaction, theaflavins, has multiple health benefits. Our bacteria can potentially also play a part in theaflavins industrial production.</p>
