| Enzyme Function | FUNCTION: Peroxidase that is able to convert a large number of compounds, but its physiological substrate is not known. Shows high reactivity towards anthraquinone dyes (e.g. Reactive Blue 19) and a modest activity towards standard peroxidase substrates (such as guaiacol and 2,6-dimethoxyphenol) and azo dyes (e.g. Reactive Blue 5). Is also able to oxidize aromatic sulfides enantioselectively, resulting in the corresponding (R)-sulfoxides, but with a poor efficiency. Does not display catalase activity. {ECO:0000269|PubMed:19967355}. |
| Temperature Dependency | BIOPHYSICOCHEMICAL PROPERTIES: Temperature dependence: Optimum temperature is about 25 degrees Celsius. Thermostable. Retains 50% of its activity after heating 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:19967355}; |
| PH Dependency | BIOPHYSICOCHEMICAL PROPERTIES: pH dependence: Optimum pH is 3.5 with Reactive Blue 19 as substrate. {ECO:0000269|PubMed:19967355}; |
