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...

Removal of acetaminophen using enzyme-mediated oxidative coupling processes: II. Cross-coupling with natural organic matter.

13 Sep 2009 The influence of natural organic matter (NOM) on the transformation of acetaminophen in laccase-mediated oxidative coupling systems was investigated in this study. It was found that the removal of acetaminophen was enhanced while the self-coupling ... Read more...

Removal of acetaminophen using enzyme-mediated oxidative coupling processes: I. Reaction rates and pathways.

13 Sep 2009 We found that acetaminophen could be effectively transformed and removed from water by laccase-mediated oxidative coupling processes. The removal of acetaminophen followed second-order kinetics with first-order to the concentrations of both the ... 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.
