| Enzyme Function | FUNCTION: Peroxisomal catalase involved in the oxidative stress response serving to protect cells from toxicity (PubMed:25243607, PubMed:28456303). Plays a role in maintaining normal lifespan (PubMed:14996832). Plays a role in regulating the response to pathogens such as E.faecalis (PubMed:17483415). {ECO:0000269|PubMed:14996832, ECO:0000269|PubMed:17483415, ECO:0000269|PubMed:25243607, ECO:0000269|PubMed:28456303}. |
