| Enzyme Function | FUNCTION: Thiol-specific peroxidase that catalyzes the reduction of hydrogen peroxide and organic hydroperoxides to water and alcohols, respectively. Plays a role in cell protection against oxidative stress by detoxifying peroxides. Is important for survival under desiccation conditions. Not required for virulence although is necessary for nasal colonization. {ECO:0000269|PubMed:17114262}. |
