Protein attributes
| Sequence length | 335 AA. |
| Sequence status | Complete. |
| Sequence processing | The displayed sequence is further processed into a mature form. |
| Protein existence | Evidence at transcript level |
General annotation (Comments)
| Function | Removal of H2O2, oxidation of toxic reductants, biosynthesis and degradation of lignin, suberization, auxin catabolism, response to environmental stresses such as wounding, pathogen attack and oxidative stress Probable. The enzyme activity has to be proved. |
| Catalytic activity | 2 phenolic donor + H2O2 = 2 phenoxyl radical of the donor + 2 H2O. |
| Cofactor | Binds 1 heme B (iron-protoporphyrin IX) group per subunit By similarity. Binds 2 calcium ions per subunit By similarity. |
| Subcellular location | Secreted By similarity. |
| Miscellaneous | There are 73 peroxidase genes in A.thaliana. |
| Sequence similarities | Belongs to the peroxidase family. Classical plant (class III) peroxidase subfamily. |
| Caution | Lacks the distal histidine (here Ser-77), present in the active site, which is one of the conserved features of the classical plant (class III) peroxidase family. |
| Sequence caution | The sequence AAB64327.1 differs from that shown. Reason: Erroneous initiation. |
