| Enzyme Function | FUNCTION: Removal of H(2)O(2), oxidation of toxic reductants, biosynthesis and degradation of lignin, suberization, auxin catabolism, response to environmental stresses such as wounding, pathogen attack and oxidative stress. These functions might be dependent on each isozyme/isoform in each plant tissue.; FUNCTION: Plays an integral role in secondary cell wall biosynthesis by the polymerization of cinnamyl alcohols into lignin and by forming rigid cross-links between cellulose, pectin, hydroxy-proline-rich glycoproteins, and lignin. |
