A DyP-Type Peroxidase of Pleurotus sapidus with Alkene Cleaving Activity [PDF]

Molecules, 2020
Alkene cleavage is a possibility to generate aldehydes with olfactory properties for the fragrance and flavor industry. A dye-decolorizing peroxidase (DyP) of the basidiomycete Pleurotus sapidus (PsaPOX) cleaved the aryl alkene trans-anethole. The PsaPOX

Roles of distal aspartate and arginine of B-class dye-decolorizing peroxidase in heterolytic hydrogen peroxide cleavage. [PDF]

J Biol Chem, 2018
Dye-decolorizing peroxidases (DyPs) represent the most recently classified hydrogen peroxide dependent heme peroxidase family. Although widely distributed with more than 5000 annotated genes and hailed for their biotechnological potential detailed ...

Redox thermodynamics of B-class dye-decolorizing peroxidases

Journal of Inorganic Biochemistry, 2019
With >5000 annotated genes dye-decolorizing peroxidases (DyPs) represent a heme b peroxidase family of broad functional diversity. Bacterial B-class DyPs are poor peroxidases of unknown physiological function. Hydrogen peroxide efficiently mediates the rapid formation of Compound I in B-class DyPs, which, however, is stable and shows modest reactivity ...

Structural and Biochemical Characterization of a Dye-Decolorizing Peroxidase from Dictyostelium discoideum. [PDF]

Int J Mol Sci, 2021
A novel cytoplasmic dye-decolorizing peroxidase from Dictyostelium discoideum was investigated that oxidizes anthraquinone dyes, lignin model compounds, and general peroxidase substrates such as ABTS efficiently. Unlike related enzymes, an aspartate residue replaces the first glycine of the conserved GXXDG motif in Dictyostelium DyPA.

Fungal dye-decolorizing peroxidase diversity: roles in either intra- or extracellular processes. [PDF]

Appl Microbiol Biotechnol, 2022
Abstract Fungal dye-decolorizing peroxidases (DyPs) have found applications in the treatment of dye-contaminated industrial wastes or to improve biomass digestibility. Their roles in fungal biology are uncertain, although it has been repeatedly suggested that they could participate in lignin degradation and/or ...
