Tyrosinase from mushroom

Descrição detalhada : Tyrosinase is a copper-containing oxidase with activity for catechols and cresol. Tyrosinase participates in the conversion of tyrosine to dihydroxyphenylalanine (DOPA), and polymerization of DOPA leads to melanin formation. Tyrosinase has a role in browning reactions. The enzyme is said to have two binding sites for aromatic substrates and a distinct binding site for oxygen-copper., Isoelectric point (pI): 4.7-5pH optimum is 6-7Molecular weight: 128 kDa by sedimentation velocity diffusion; 133 kDa by light-scattering measurements, and 119.5 kDa by electrophoresis.Tyrosinase is a copper-containing oxidase, which has activity for both catechols and cresol. It is responsible for browning reactions. The enzyme is reported to have two binding sites for aromatic substrates and a different binding site for oxygen-copper. The copper is probably Cu(I), with inactivation involving oxidation to Cu(II) ion.
