Abstract :Laccase (E.C. 1.10.3.2) from Trametes versicolor has been electrochemically immobilized on the layer of electropolymerized polyaniline entrapped in a thin silica sol-gel film deposited onto a graphite electrode. The magnitude of redox peaks of the cyclic voltammogram observed for the laccase-modified electrode has been found to vary remarkably with the electropolymerization conditions. It could be presumed that the conductivity of polyaniline would exert considerable effects on the direct electron transfer between the enzyme molecule and the electrode surface. The electrochemical parameters obtained by cyclic voltammometry have showed a pH dependence, and it was suggested from the results that the binding of copper ion in the active center of laccase might become appreciably loose at pH 3.0.
