Unveiling the mechanism of dye-decolorizing peroxidase (DyP): unique anthraquinone-directed catalysis exposes a dual-function peroxidase

-DyP4, encompassing both peroxidase-mediated oxidation and hydrolytic cleavage. Elucidating this dual chemistry not only redefines the catalytic behavior of the DyP family but also provides a mechanistic cornerstone for engineering robust biocatalysts to eliminate recalcitrant dye pollutants in industrial wastewater.
