| 释义 | BETA Examples of tyrosinasetyrosinase isn’t in the Cambridge Dictionary yet. You can help! As mentioned above, a sequence analysis indicates that tyrosinase may have only five histidines and that the sixth ligand could be another one. Tyrosinase expression during neuroblast divisions affects later pathfinding by retinal ganglion cells. In the next step dioxygen forms a bridging bond between the cofactor and iron, which is quite similar to a corresponding step in tyrosinase (see above). It is usually the result of a genetic mutation causing the absence of tyrosinase, an enzyme essential for melanin synthesis.

Especially the structural mimicry of certain copper proteins (e.g. hemocyanin, tyrosinase and catechol oxidase), containing so-called type-3 copper binding sites, has been shown.

Another study found that glutathione inhibits melanin formation by direct inactivation of the enzyme tyrosinase by binding and chelating copper within the enzymes active site.

The plant contains substances which inhibit production of tyrosinase, an enzyme which catalyzes the production of melanin. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Mice and other mammals without tyrosinase have unpigmented pink skin, unpigmented white hair, unpigmented reddish eyes, and some form of vision impairment.

From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. The pointed pattern is a form of partial albinism, resulting from a mutation in tyrosinase, an enzyme involved in melanin production. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. One example is an enzyme called tyrosinase that, when expressed at high levels, transforms certain skin cells (e.g. melanocytes) into tumors called melanomas.

The plant contains substances which inhibit production of tyrosinase an enzyme which catalyzes the production of melanin. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. The key enzyme in melanin synthesis is tyrosinase. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. This had long been thought to be due to a mutation in the gene for the tyrosinase enzyme. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. The mutation in the tyrosinase also results in abnormal neurological connections between the eye and the brain. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. In humans, tyrosinase is sorted into melanosomes and the catalytically active domain of the protein resides within melanosomes. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Loss of melanogenesis function is linked to the gene that encodes tyrosinase.
