This review concerns copper-containing oxidases--laccases. Principal biochemical and electrochemical properties of laccases isolated from different sources are described, as well as their structure and mechanism of catalysis. Possible applications of laccases in different fields of biotechnology are discussed.

An analysis of the scientific literature published in the last 10 years reveals a constant growth of laccase applicative research in several industrial fields followed by the publication of a great number of patents. The Green Chemistry journal devoted the cover of its September 2014 issue to a laccase as greener alternative for chemical oxidation ...

Antioxidants determination with laccase
Talanta, 2007The spectrophotometric method of antioxidants determination using recombinant laccase Polyporus pinsitus (rPpL) and Myceliophthora thermophila (rMtL) was developed. The method includes simultaneous oxidation of the antioxidant and high reactive laccase substrate producing chromophoric radical cation.

Thermotolerant and thermostable laccases
Biotechnology Letters, 2009Laccases are phenol-oxidizing, usually four-copper containing metalloenzymes. For industrial and biotechnological purposes, laccases were among the first fungal oxidoreductases providing larger-scale applications such as removal of polyphenols in wine and beverages, conversion of toxic compounds and textile dyes in waste waters, and in bleaching and ...

Laccases and their occurrence in prokaryotes
Archives of Microbiology, 2003Laccases are copper-containing proteins that require O(2) to oxidize phenols, polyphenols, aromatic amines, and different non-phenolic substrates by one-electron transfer, resulting in the formation of reactive radicals. Although their specific physiological functions are not completely understood, there are several indications that laccases are ...

Laccase activity and putative laccase genes in marine-derived basidiomycetes
Fungal Biology, 2010Studies of laccases from marine-derived fungi are limited. In the present work, putative laccase genes from three marine-derived basidiomycetes and their laccase activities were evaluated. High amounts of laccase were produced by the fungal strains Marasmiellus sp. CBMAI 1062 (971.2UL⁻¹) and Peniophora sp.

Laccases: a never-ending story
Cellular and Molecular Life Sciences, 2009Laccases (benzenediol:oxygen oxidoreductases, EC 1.10.3.2) are blue multicopper oxidases that catalyze the oxidation of an array of aromatic substrates concomitantly with the reduction of molecular oxygen to water. In fungi, laccases carry out a variety of physiological roles during their life cycle. These enzymes are being increasingly evaluated for a

Laccase and Laccase‐Mediated Systems in the Synthesis of Organic Compounds
Advanced Synthesis & Catalysis, 2014AbstractLaccase, a blue multicopper oxidase, has recently received considerable attention because of its usefulness in oxidizing phenolic and non‐phenolic compounds, as well as its suitability for organic synthesis, environmental pollutant treatment, and other biotechnological applications. This review covers recent studies on the structural properties,

Laccases (benzenediol oxygen oxidoreductases, EC 1.10.3.2) are polyphenol oxidases (PPO) that catalyze the oxidation of various substituted phenolic compounds by using molecular oxygen as the electron acceptor. The ability of laccases to act on a wide range of substrates makes them highly useful biocatalysts for various biotechnological applications ...

Laccase fromPleurotus ostreatus
Biotechnology Letters, 1986Laccase was purified from culture broth ofPleurotus ostreatus mycelium. The enzyme was a single protein of Mr 59000, pI 2.9 and was active on o-diphenyl substrates. Amino acid composition and N-terminal sequence (15 residues) were determined. Polyclonal anti-laccase antibodies were obtained.
