Albinism in the domestic cat (Felis eatus) is associated with a tyrosinase
To further verify the control point of VZ-EO on B16 melanin production, we analyzed the protein expression of tyrosinase
by western blot analysis, and the results are displayed in Figure 3(b).
Bacteria as a Source of Tyrosinase
. Streptomyces tyrosinases
are the most thoroughly characterized enzymes of bacterial origin [22, 23].
Similar enzyme activation and catalysis in hemocyanins and tyrosinases
. Gene 398: 183-191.
inhibitory activity of the two NSS oil samples are presented in Table 3.
Prevention of Agaricus bisporus postharvest browning with tyrosinase
activity assay was carried out according to previous literature with minor modification (22).
There is a positive correlation between phenolic content and tyrosinase
It is a weak, reversible, and competing tyrosinase
In previous reports, the inhibitory effect of Salvia miltiorrhiza and Carthamus tinctorius on tyrosinase
has been validated [13-15]; however, the active constituents with tyrosinase
inhibition activity have not been clearly reported yet.
, caffeic acid, p-coumaric acid, and sodium dihydrogen phosphate were from Sigma-Aldrich (Saint Louis, MO, USA).
Reasons for its skin lightening effect include: its antioxidant properties, ability to switch eumelanin to pheomelanin which is the type of melanin found in lighter skin-toned individuals and the inhibitory effect it has on tyrosinase
which is a key enzyme in melanogenesis.2
