| 11. | From the blood of Bombyx mori, V . von Ducceshi has also obtained a tyrosinase.
|
| 12. | The activity of tyrosinase is similar to catechol oxidase, a related class of copper oxidase.
|
| 13. | Polyphenol oxidases are a family of di-copper metalloenzymes that include tyrosinase and catechol oxidase.
|
| 14. | No mutations of the tyrosinase or " C " gene are known in horses.
|
| 15. | Copper is needed by the body for a dopamine ?-hydroxylase, superoxide dismutase and tyrosinase.
|
| 16. | In both cases inactive proenzymes such as hemocyanin, tyrosinase, and catcholoxidase must be activated first.
|
| 17. | CREB and Mitf directly enhance melanin production by raising levels of tyrosinase and other melanin biosynthetic enzymes.
|
| 18. | An example of such a protein is the enzyme tyrosinase, which is required for melanin production.
|
| 19. | Normally tyrosinase is produced in minute quantities but its levels are very much elevated in melanoma cells.
|
| 20. | The mechanism of action of BW-723C86 is decreasing the inhibits the activity of tyrosinase . }}
