Kinetics of Mushroom Tyrosinase and Melanogenesis Inhibition by N-Acetyl-pentapeptides

Figure 1

Inhibitory effects of the N-acetyl-pentapeptides on mushroom tyrosinase. (a) to (d) are progress curves of Ac-P1 to Ac-P4 for the oxidation of L-DOPA by the tyrosinase. The concentrations of inhibitor for curves 1–5 were 0, 0.1, 0.2, 0.5, and 1 mg/mL, respectively.
