Function |
Removal of H(2)O(2), oxidation of toxic reductants |
Propagated annotation
[?]
case <FTGroup:1> and <FTGroup:2> and <FTGroup:3> and <FTTag:viacarbo>
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. |
Catalytic activity |
Reaction=AH2 + H2O2 = A + 2 H2O; Xref=Rhea:RHEA:30275, ChEBI:CHEBI:13193, ChEBI:CHEBI:15377, ChEBI:CHEBI:16240, ChEBI:CHEBI:17499;. |
Cofactor |
heme b Note: Binds 1 heme b (iron(II)-protoporphyrin IX) group per subunit. |
|
Ca(2+) Note: Binds 2 calcium ions per subunit. |
Subcellular location |
Secreted. |
Similarity |
Belongs to the peroxidase family. Classical plant (class III) peroxidase subfamily. |
