  1. Gene annotation: Laccases and multicopper oxidases 4th Workshop of the Laccaria Genome Consortium Georg-August-Universität, Göttingen - November 16-17, 2006 P.J. Hoegger1, S. Kilaru1, P.E. Courty2, F. Martin2, U. Kües1 1Georg-August-University Göttingen, Germany 2INRA Nancy, France

  2. Multi-copper oxidase family main members: - laccases - fungi - plants - insects - bacteria - ascorbate oxidases - plants - ferroxidases - fungi - ceruloplasmins - mammals

  3. Laccase function and application Biological functions: - lignin degradation - lignification - pigment synthesis - fruiting body formation - melanin polymerization - detoxification - cuticle sclerotization - soil litter polymer degrad. Applications: - bleaching processes - bioremediation - composite wood production
