RT from Zinnia elegans, an enzyme involved in lignin biosynthesis.";
RL Plant Physiol. 139:1138-1154(2005).
CC -!- FUNCTION: Removal of H(2)O(2), oxidation of toxic reductants,
CC biosynthesis and degradation of lignin, suberization, auxin catabolism,
CC response to environmental stresses such as wounding, pathogen attack
CC and oxidative stress. These functions might be dependent on each
CC isozyme/isoform in each plant tissue. Involved in the synthesis of
CC highly polymerized lignins.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=2 a phenolic donor + H2O2 = 2 a phenolic radical donor + 2
CC H2O; Xref=Rhea:RHEA:56136, ChEBI:CHEBI:15377, ChEBI:CHEBI:16240,

CC Evidence={ECO:0000269|PubMed:16258008};
CC -!- COFACTOR:
CC Name=heme b; Xref=ChEBI:CHEBI:60344;
CC Evidence={ECO:0000255|PROSITE-ProRule:PRU00297};
CC Note=Binds 1 heme b (iron(II)-protoporphyrin IX) group per subunit.
CC {ECO:0000255|PROSITE-ProRule:PRU00297};
CC -!- COFACTOR:
CC Name=Ca(2+); Xref=ChEBI:CHEBI:29108;
CC Evidence={ECO:0000255|PROSITE-ProRule:PRU00297};
CC Note=Binds 2 calcium ions per subunit. {ECO:0000255|PROSITE-
CC ProRule:PRU00297};
CC -!- BIOPHYSICOCHEMICAL PROPERTIES:
CC Kinetic parameters:
CC KM=241 uM for p-coumaryl alcohol (in the presence of 10.2 uM H2O2,
CC for a partially glycosylated enzyme) {ECO:0000269|PubMed:16258008};
CC KM=432 uM for p-coumaryl alcohol (in the presence of 10.2 uM H2O2,
CC for a fully glycosylated enzyme) {ECO:0000269|PubMed:16258008};
CC KM=83 uM for coniferyl alcohol (in the presence of 10.2 uM H2O2, for
CC a partially glycosylated enzyme) {ECO:0000269|PubMed:16258008};
CC KM=124 uM for coniferyl alcohol (in the presence of 10.2 uM H2O2, for
CC a fully glycosylated enzyme) {ECO:0000269|PubMed:16258008};
CC KM=15 uM for sinapyl alcohol (in the presence of 10.2 uM H2O2, for a
CC partially glycosylated enzyme) {ECO:0000269|PubMed:16258008};
CC KM=13 uM for sinapyl alcohol (in the presence of 10.2 uM H2O2, for a
CC fully glycosylated enzyme) {ECO:0000269|PubMed:16258008};
CC Note=The full glycosylation reduces the affinity of the enzyme for
CC both p-coumaryl and coniferyl, but not sinapyl, alcohol.;
CC -!- SUBCELLULAR LOCATION: Secreted {ECO:0000255|PROSITE-ProRule:PRU00297}.
CC -!- TISSUE SPECIFICITY: Expressed in tracheary elements, roots, young and
CC old hypocotyls, and stems in the partially glycosylated form and in
CC roots and young hypocotyls in the fully glycosylated form. None of the
CC isoforms is significantly expressed in leaves or cotyledons.
CC {ECO:0000269|PubMed:16258008}.
CC -!- PTM: N-glycosylated.
CC -!- MASS SPECTROMETRY: Mass=31460; Method=MALDI; Note=Deglycosylated form.;
CC Evidence={ECO:0000269|PubMed:16258008};
CC -!- MASS SPECTROMETRY: Mass=33440; Method=MALDI; Note=Partially
CC glycosylated form.; Evidence={ECO:0000269|PubMed:16258008};
CC -!- MASS SPECTROMETRY: Mass=34700; Method=MALDI; Note=Fully glycosylated
CC form.; Evidence={ECO:0000269|PubMed:16258008};
CC -!- SIMILARITY: Belongs to the peroxidase family. Classical plant (class
CC III) peroxidase subfamily. {ECO:0000255|PROSITE-ProRule:PRU00297}.
CC -!- CAUTION: Four genes are encoding the same mature protein that may have
CC different glycosylation degree. The two precursors produced differ by
CC only one amino acid located in the signal peptide. {ECO:0000305}.
