Protein attributes
| Sequence length | 329 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. These functions might be dependent on each isozyme/isoform in each plant tissue. |
| Catalytic activity | Donor + H2O2 = oxidized 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. |
Ontologies
Alternative products
| This entry describes 1 isoform produced by alternative splicing. [Select] Note: A number of isoforms are produced. According to EST sequences. | ||||||
| Isoform 1 (identifier: Q9SZE7-1) This isoform has been chosen as the 'canonical' sequence. All positional information in this entry refers to it. This is also the sequence that appears in the downloadable versions of the entry. |
