Lignin degradation and detoxification of lignin-derived products (By similarity). Has activity towards 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) (PubMed:34093489). 4 hydroquinone + O2 = 4 benzosemiquinone + 2 H2O Binds 4 Cu cations per monomer. Activity is strongly promoted by toluene (PubMed:34093489). Activity is promoted by magnesium, potassium, cadmium, zinc, nickel, sodium, lead and manganese ions (PubMed:34093489). Completely inhibited by IAA (cysteine protease inhibitor), PMSF (serine protease inhibitor), DEP (histidine protease inhibitor) and NAI (tyrosine protease inhibitor) (PubMed:34093489). Inhibited by ethanol, acetone, SDS, and EDTA (PubMed:34093489). Activity is strongly inhibited by mercury ions (PubMed:34093489). Also inhibited by lithium, aluminum, calcium, barium and iron ions (PubMed:34093489). kcat is 129.37 sec(-1) for ABTS oxidation (at pH 6.0 and 50 degrees Celsius). Optimum pH is 6 at 25 degrees Celsius (PubMed:34093489). Retains over 60 percent activity in the pH range from 4 to 10 (PubMed:34093489). Retains activity above 50% after incubation at pH 5-10 for 72 hours (PubMed:34093489). Optimum temperature is 50 degrees Celsius (PubMed:34093489). Retains over 57 percent activity when incubated for 2 hours at temperatures between 30-65 degrees Celsius (PubMed:34093489). Monomer. Able to metabolize the endocrine disrupting chemical (EDC) 17beta-estradiol (E2), and so could be used in biotechnological and industrial applications that require the biodegradation and bioremediation of the environmental pollutant. Belongs to the multicopper oxidase family.
