| 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:23111597}. |
| Temperature Dependency | BIOPHYSICOCHEMICAL PROPERTIES: Temperature dependence: Thermostable. Retains 50%-90% of its activity after heating for 2 hours at 60 degrees Celsius, while no decrease in activity is observed within the same time at 30 or 40 degrees Celsius. {ECO:0000269|PubMed:23111597}; |
| PH Dependency | BIOPHYSICOCHEMICAL PROPERTIES: pH dependence: Optimum pH is 4 with 2,6-dimethoxyphenol as substrate. Retains 90% of its activity after 4 hours at pH 2.5. {ECO:0000269|PubMed:23111597}; |
