Functionality study of Na6PMo11FeO40 as a mushroom tyrosinase inhibitor

Tyrosinase is encoded by multi-gene family (Richter et al., 2012), the molecular weight are usually 30-34 kDa (Bernan et al., 1985), 42-46 kDa (Gerdemann et al., 2002; Wichers et al., 2003), 64-68 kDa (Wichers et al., 2003). Figure A is the electrophoresis analysis of protein molecular weight and species of mushroom tyrosinase, figure B is the inhibitory spectrum of Native-PAGE of PMo11Fe on mushroom tyrosinase. The figures confirm that three kinds of molecular weight of tyrosinase are all existed in the sample and with activity.
