Recombinant tyrosinase from Streptomyces avermitilis MA4680, MelC2 (gi:499291317), was heterologously expressed in Escherichia coli BL21 (DE3). The expression level of active MelC2 was increased by the codon-optimized MelC1 caddie protein (KP198295.1). By performing saturation mutagenesis of the Y91 residue of MelC1, it was found that aromatic residues such as Y, F, and W at the 91st position help produce a correctly folded conformation of MelC2. The recombinant MelC2 was utilized as a… CONTINUE READING
