| Enzyme Function | FUNCTION: Manganese-independent peroxidase that is able to convert a large number of compounds, but its physiological substrate is not known. In addition to classic peroxidase substrates (e.g. 2,6-dimethoxyphenol), oxidizes dyes such as Reactive Blue 5 and Reactive Black 5. {ECO:0000269|PubMed:19756587, ECO:0000269|PubMed:23111597, ECO:0000269|PubMed:25153532, ECO:0000269|PubMed:25495127, ECO:0000269|PubMed:25542606}. |
| Temperature Dependency | BIOPHYSICOCHEMICAL PROPERTIES: Temperature dependence: Retains >80% activity after incubation at temperatures up to 60 degrees Celsius for 10 minutes. Retains 50% activity after incubation at 65.5 degrees Celsius for 10 minutes. Activity is lost after incubation at 70 degrees Celsius for 10 minutes. {ECO:0000269|PubMed:25153532}; |
| PH Dependency | BIOPHYSICOCHEMICAL PROPERTIES: pH dependence: Optimum pH is 4.5 for oxidation of 2,6-dimethoxyphenol (PubMed:23111597). Retains 100% activity after incubation at pH 2.5 for 4 hours (PubMed:23111597, PubMed:19756587, PubMed:25153532). Retains >60% activity after incubation at pH 2-11 at 4 degrees Celsius (PubMed:25153532). Retains >60% activity after incubation at pH 3-9 at room temperature (PubMed:25153532). {ECO:0000269|PubMed:19756587, ECO:0000269|PubMed:23111597, ECO:0000269|PubMed:25153532}; |
