Activation of laccase by penicillin and derivatives

Process Biochemistry, 2006
Abstract Capable of oxidizing a wide range of reducing substances, laccase has a great potential for various biocatalytic applications. Extensive research effort is being made for improving laccase's activity, specificity, and stability. We observed that pre-incubating with penicillin led to a significant activation of a Rhizoctonia solani laccase,

Laccase Activity in Trichoderma virens

2011
Fungal laccases are involved in multiple functions, such as lignin degradation, pigments (melanin) synthesis and degradation, detoxification and pathogenesis. Furthermore, they are useful biocatalysts for several biotechnological applications.The laccase gene function was previously analysed in Trichoderma virens, an effective biocontrol agent: six ...

Optimization of a Small Laccase by Active‐Site Redesign

ChemBioChem, 2013
Small but faster: A small laccase from Streptomyces coelicolor (SLAC) has been engineered by structure-based design and site-directed mutagenesis to improve the activity on commercially relevant substrates. The variants generated showed up to 40-fold increased efficiency on 2,6-dimethoxyphenol and the ability to use mediators with considerably higher ...

Activity and stability of laccase in conjugation with chitosan

International Journal of Biological Macromolecules, 2005
Laccase is one of a few enzymes that can directly reduce oxygen into water under ambient conditions, while oxidizing a variety of aromatic compounds. Its conjugation with chitosan generates a pH-sensitive functional biomaterial that changes its solubility in response to pH variation.

Dihydrobenzofuran Neolignanamides: Laccase-Mediated Biomimetic Synthesis and Antiproliferative Activity

Journal of Natural Products, 2016
The biomimetic synthesis of a small library of dihydrobenzofuran neolignanamides (the natural trans-grossamide (4) and the related compounds 21-28) has been carried out through an eco-friendly oxidative coupling reaction mediated by Trametes versicolor laccase.

Impact of enological tannins on laccase activity

2021
Los taninos enológicos se utilizan habitualmente en la elaboración del vino por diversos motivos (Versari et al., 2013; Vignault et al., 2018), entre los que destacan su acción inhibitoria de la actividad lacasa en las vendimias afectadas por la podredumbre gris y la protección del color del vino frente al pardeamiento. No obstante, hasta hace muy poco

Biomimetic Electrochemical Sensor Based on Single-Atom Nickel Laccase Nanoenzyme for Quercetin Detection.

Analytical Chemistry
Laccase, a member of the copper oxidase family, has been used as a green catalyst in the environmental and biochemical industries. However, laccase nanoenzymes are limited to materials with copper as the active site, and noncopper laccase nanoenzymes ...

Laccase in pulp activation and functionalisation

2006
The presence of surface lignin in pulp fibres offers possibilities to enhance the existing pulp properties or even to create completely new pulp properties by enzymatic means. Improving the properties of wood fibres is a constant interest of pulp, paper and board manufacturing industry. New methods for targeted modification of wood materials could also
