Bifunctional Polyphenol Oxidases: Novel Functions in Plant Pigment Biosynthesis

Enzymes in search of a function, for polyphenol oxidases (PPOs), described as such, this situation has changed recently. A tyrosinase is involved in betacyanin biosynthesis in common portulaca (see picture) and red beet, and a chalcone‐specific PPO is responsible for the formation of aurones in yell...

Zusammenfassung:Enzymes in search of a function, for polyphenol oxidases (PPOs), described as such, this situation has changed recently. A tyrosinase is involved in betacyanin biosynthesis in common portulaca (see picture) and red beet, and a chalcone‐specific PPO is responsible for the formation of aurones in yellow snapdragon flowers.
