A new laccase enzyme from a white-rot fungus Trametes sp. MA-X01 was studied. The enzyme has a molecular weight of 62 kDa and works best at 60°C. It remains stable at high temperatures and can function in a wide pH range (3.0-5.0). Certain metals like Mg2+, Mn2+, Zn2+, and Cu2+ boost its activity, while chemicals like β-mercaptoethanol inhibit it. The laccase efficiently decolorizes various types of dyes without needing an additional chemical mediator.
