Protein attributes
| Sequence length | 492 AA. |
| Sequence status | Complete. |
| Protein existence | Evidence at transcript level |
General annotation (Comments)
| Function | Occurs in almost all aerobically respiring organisms and serves to protect cells from the toxic effects of hydrogen peroxide. |
| Catalytic activity | 2 H2O2 = O2 + 2 H2O. |
| Cofactor | Heme group. |
| Subunit structure | Homotetramer and heterotetramer. At least six or seven isozymes are produced from a mixture of 3 gene products. |
| Subcellular location | |
| Sequence similarities | Belongs to the catalase family. |
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: P25819-1) 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. |
