| Enzyme Function | FUNCTION: Decomposes hydrogen peroxide into water and oxygen; serves to protect cells from the toxic effects of hydrogen peroxide. Involved in resistance to paraquat when fur is absent and to tert-butyl hydroperoxide. Is important for survival under glucose starvation and desiccation conditions. Not required for virulence although is necessary for nasal colonization. {ECO:0000269|PubMed:11349039, ECO:0000269|PubMed:17114262}. |
