Purification and Partial Characterization of a Laccase from the White Rot Fungus Phanerochaete flavido-alba

摘要

In addition to excreting lignin-degrading peroxidases, the white rot fungus Phanerochaete flavido-alba also excretes a laccase. This protein was purified to homogeneity and found to have a molecular weight of 94,000 and an isoelectric point lower than 3.55. Its UV-visible spectrum is typical of copper-containing proteins.
