LACCASE FROM THE WHITE-ROT FUNGUS TRAMETES TROGII

The white-rot fungus Trametes trogii excretes a main laccase showing a molecular mass of 70 kDa, acidic isoelectric point and N-terminal seq uence homologous to that of several phenol oxidases. The purified enzy me oxidizes a number of phenolic and non-phenolic compounds; recalcitr ant molecules may be converted into substrates by introducing, in the correct position, o- or p-orienting ring-activating groups.
