Genetic organization and biochemical properties of the P. flavido- alba characterize this enzyme as member of a new subfamily of laccases

Basidiomycete laccases are being exploited because of their oxidizing abilities and stability. The production of recomnbinant laccases for industrial application is limited because (between other reasons) of unpredictable changes during laccase production in heterologous hosts.

The characterization of Phanerochaete flavido-alba laccase as a member of a new subfamily of multicopper oxidases add new interest to the applied and basic research on laccases. P. flavido-alba ( a basidiomycete) laccase production seems to be regulated by a mechanism(s) more complex than the assumed as general for laccase production in basidiomycetes

As the best know ligninolytic fungi (P. chrysosporium), P. flavido alba is ligninolytic. In addition is the only member of the Phanerochaete genus producing amounts of laccase for applied studies. Now, P. flavido-alba is revealed an excellent model to gain new knowledge in ligninolysis and environmental and industrial applications of these fungus.
