The pro form of recombinant tyrosinase from Aspergillus oryzae (melB) shows no catalytic activity, but acid treatment (around pH 3.5) of protyrosinase activates it to induce tyrosinase activity. Circular dichroism spectra, gel filtration analysis, an

The pro form of melB tyrosinase from the melB gene of Aspergillus oryzae was over-produced from E. coli and formed a homodimer that exhibited the spectral features of met-tyrosinase. In the presence of NH(2)OH (reductant), the proenzyme bound dioxyge
