Widespread occurrence of expressed fungal secretory peroxidases in forest soils.

open access: yesPLoS ONE, 2014
Fungal secretory peroxidases mediate fundamental ecological functions in the conversion and degradation of plant biomass. Many of these enzymes have strong oxidizing activities towards aromatic compounds and are involved in the degradation of plant cell ...

Biochemical features of dye‐decolorizing peroxidases: Current impact on lignin degradation [PDF]

open access: yesBiotechnology and Applied Biochemistry, 2020
AbstractDye‐decolorizing peroxidases (DyP) were originally discovered in fungi for their ability to decolorize several different industrial dyes. DyPs catalyze the oxidation of a variety of substrates such as phenolic and nonphenolic aromatic compounds.

Enantioselective Synthesis of Dilignol Model Compounds and Their Stereodiscrimination Study with a Dye-Decolorizing Peroxidase. [PDF]

open access: yesOrg Lett, 2017
A four-step enantioselective approach was developed to synthesize anti (1R,2S)-1a and (1S,2R)-1b containing a β-O-4 linkage in good yields. A significant difference was observed for the apparent binding affinities of four stereospecific lignin model compounds with TcDyP by surface plasmon resonance, which was not translated into a significant ...

Redox thermodynamics of B-class dye-decolorizing peroxidases

open access: yesJournal 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 ...

Decolorization of selected azo dye by W1B6: Biodegradation optimization, isotherm, and kinetic study biosorption mechanism

open access: yesAdsorption Science & Technology, 2019
This study reports on the evaluation of biodegradation and biosorption mechanism of indigenous bacteria on azo dye decolorization. The bacterial strains were screened for their ability in decolorizing of selected toxic azo dyes in aqueous solution ...

Design and Engineering of an Efficient Peroxidase Using Myoglobin for Dye Decolorization and Lignin Bioconversion [PDF]

open access: yesInternational Journal of Molecular Sciences, 2021
The treatment of environmental pollutants such as synthetic dyes and lignin has received much attention, especially for biotechnological treatments using both native and artificial metalloenzymes. In this study, we designed and engineered an efficient peroxidase using the O2 carrier myoglobin (Mb) as a protein scaffold by four mutations (F43Y/T67R/P88W/

Mechanistic Insights into Dye-Decolorizing Peroxidase Revealed by Solvent Isotope and Viscosity Effects. [PDF]

open access: yesACS Catal, 2017
Dye-decolorizing peroxidases (DyPs) are a family of H2O2-dependent heme peroxidases, which have shown potential applications in lignin degradation and valorization. However, the DyP kinetic mechanism remains underexplored. Using structural biology and solvent isotope (sKIE) and viscosity effects, many mechanistic characteristics have been uncovered for
