Characteristics of the protein coding sequence
Polyphenol oxidase 5
EN
The PPO enzyme family catalyses the o-hydroxylation of monophenol molecules in which the benzene ring contains a single hydroxyl substituent) to o-diphenols (phenol molecules containing two hydroxyl substituents). It can also further catalyse the oxidation of o-diphenols to produce o-quinones.

PPO causes the rapid polymerization of o-quinones to produce black, brown or red pigments (polyphenols) that cause fruit browning

Additional Information
Downregulation of the Ppo5 gene results in reduced susceptibility to black spot bruise development.
