| − | To validate the functionality of the tyrosinase TyrVs, we designed bacteria expressing TyrVs.We constructed the pET-SUMO-TyrVs vector, after culturing at 16°C for 20 hours, extracted the proteins for SDS-PAGE and Coomassie Brilliant Blue staining analysis.
| |
| − | We purified SUMO-TyrVs using a HiTrap Ni-NTA column. The purified protein was verified by SDS-PAGE and was found to be present in the 50 mM imidazole elution fraction.
| |
| − | We conducted tests on the reactions from tyrosine to dopaquinone and from L-DOPA to dopaquinone. The experiment of enzymatic reaction from tyrosine to dopaquinone was conducted at 37°C with an enzyme concentration of 0.1 μg/mL. The calculated Michaelis constant (Km) and maximum velocity (Vmax) were 456.8 μmol/L and 0.31 μmol/L·s, respectively. The experiment of enzymatic reaction from L-DOPA to dopaquinone was conducted at 37°C with an enzyme concentration of 0.2 μg/mL. The calculated Michaelis constant (Km) and maximum velocity (Vmax) were 8787 μmol/L and 0.86 μmol/L·s, respectively.
