Induction of Tyrosinase in Higher Fungi

Naturevolume 207pages753754 (1965) | Download Citation



TYROSINASE is a common enzyme in mycelia and fruit bodies of several fungi. In contrast to laccase it is a typical endoenzyme which is not excreted into the culture medium. In some fungi its occurrence is inconstant and dependent on the stage of development of the mycelium. Whereas in Phellinus laevigatus, Inonotus cuticularis and I. obliquus tyrosinase can be found in young mycelia, in Phellinus ribis and Gloeoporus adustus its activity increases with the ageing of the hyphae. In some fungi (Fomes marginatus, Lentinus lepideus, Piptoporus betulinus) tyrosinase is only present under special cultural conditions, but it can be induced by several chemicals, which are not substrates for this enzyme.
