Biocatalyzed Generation of Molecular Diversity: Selective Modification of the Saponin Asiaticoside
TL;DR: An array of different derivatives of the complex ursane-type triterpene glycoside asiaticoside, a saponin component isolated from the perennial herb Centella asiaticsa, was generated by exploiting the stereo-, regio- and site-selectivity of four groups of enzymes.
Laccase immobilization on copolymer of butyl acrylate and ethylene glycol dimethacrylate
TL;DR: In this article, an enzyme-carrier preparation of the wood-rotting fungus Cerrena unicolor was found to have very high activity and storage stability in a packed bed reactor at 30°C.

Potential of Trametes maxima IIPLC-32 derived laccase for the detoxification of phenolic inhibitors in lignocellulosic biomass prehydrolysate
Sunil Kumar Suman,Sunil Kumar Suman,Maneesha Khatri,Manisha Dhawaria,Akhilesh Kumar Kurmi,Deepshikha Pandey,Sanjoy Ghosh,Suman L. Jain +7 more
TL;DR: A high potential of Trametes maxima IIPLC-32 laccase for industrial applications is indicated because of its stability in the pH range 2–5 and temperature of 50–70 °C with ABTS and elevated level of tolerance to inhibitors like sodium azide.

Albino A. Dias,Ana Sampaio,Rui M. F. Bezerra +2 more
- 01 Jan 2007
TL;DR: The use of constructed wetlands is a low cost technique, with low maintenance needs as discussed by the authors, which is able to tolerate high fluctuations in flow, temperature, and the composition and/or concentration of pollutants in wastewater.

Multicopper Oxidases and Oxygenases
TL;DR: Copper sites have historically been divided into three classes based on their spectroscopic features, which reflect the geometric and electronic structure of the active site: type 1 or blue copper, type 2 (T2) or normal copper, and type 3 (T3) or coupled binuclear copper centers.

Polyphenol oxidases in plants
Alfred M. Mayer,Eitan Harel +1 more
TL;DR: Two main groups of plant polyphenol oxidases are recognized: the catecholoxidases and the laccases: their purification, subcellular location and protein properties are described.

Elias Abadulla,Tzanko Tzanov,Silgia A. Costa,Karl-Heinz Robra,Artur Cavaco-Paulo,Georg Gübitz +5 more
TL;DR: Tametes hirsuta and a purified laccase from this organism were able to degrade triarylmethane, indigoid, azo, and anthraquinonic dyes and reduced their toxicities by up to 80%.
