    Kinetic properties of tyrosinase immobilized on a polymeric membrane for the production of l-3,4-dihydroxyphenylalanine (l-DOPA) were investigated. A comparison with the properties shown by the free enzyme used in a stirred tank reactor was also carried out. The values of the Michaelis-Menten constant indicated that the immobilized tyrosinase exhibited better affinity for the substrate (Km=1.56 mM and 2.10 mM for the immobilized and free enzyme, respectively).
