Essential role of the C-terminus in Melanocarpus albomyces laccase for enzyme production, catalytic properties and structure.

22 Sep 2009 The C-terminus of the fungal laccase from Melanocarpus albomyces (MaL) is processed during secretion at a processing site conserved among the ascomycete laccases. The three-dimensional structure of MaL has been solved as one of the first complete ... Read more...

Laccase-mediated synthesis of novel substituted phenoxazine chromophores featuring tuneable water solubility.

15 Aug 2009 Laccases are members of the blue copper oxidases family found in nature. They commonly oxidise a wide range of phenol and aniline derivatives, which in turn are involved in oxidative coupling reactions. Yet, laccases remain rarely described as ... Read more...

Characterization of endogenous and recombinant forms of laccase-2, a multicopper oxidase from the tobacco hornworm, Manduca sexta.

30 Jun 2009 Laccases belong to the group of multicopper oxidases that exhibit wide substrate specificity for polyphenols and aromatic amines. They are found in plants, fungi, bacteria, and insects. In insects the only known role for laccase is in cuticle ... Read more...

Technical information about 'Laccase'

Definition: A copper-containing oxidoreductase enzyme that catalyzes the oxidation of 4-benzenediol to 4-benzosemiquinone. It also has activity towards a variety of O-quinols and P-quinols. It primarily found in FUNGI and is involved in LIGNIN degradation, pigment biosynthesis and detoxification of lignin-derived products.
