Title

Other claims from this paper (8)
- Observation The anionic peroxidase localized to suberizing tissues.
- Observation The anionic peroxidase preferred feruloyl substrates over caffeoyl, p-coumaryl and syringyl substrates.
- Observation Side chain derivatization had little influence on oxidation.
- Observation Hydroxycinnamates were preferred over their corresponding alcohols.
- Association The substrate specificity pattern was consistent with natural substrate incorporation into potato wound suberin.
- Observation Cationic peroxidases occurred in both suberizing and nonsuberizing potato tissues.
- Observation Cationic peroxidases did not discriminate between hydroxycinnamates and their alcohols.
- Observation The polymer made with purified anionic peroxidase showed substantial C-8 cross-linking while retaining unsaturation.
