Tyrosinase is an enzyme that catalyzes the production of melanin, the pigment responsible for skin, hair, and eye color. It plays a crucial role in protecting the skin from UV radiation by producing melanin to help absorb and scatter harmful rays.

What enzyme converts tyrosine into melanin?

The enzyme responsible for converting tyrosine into melanin is tyrosinase. Tyrosinase catalyzes the reactions that lead to the production of melanin, the pigment responsible for skin, hair, and eye color.


What food contains tyrosinase?

I looked it up at Answers.com (http://www.answers.com/tyrosinase?cat=health) Appears that TYROSINASE is contained in some fruits and vegetables (like apples, or potatoes; the entry in Answers.com also explains that this enzyme is responsible for the dark colour produced when cut raw food is exposed to air.


What is the optimum pH for tyrosinase?

The optimum pH for tyrosinase activity is typically around pH 6.5 to 7.5. This enzyme functions best in slightly acidic to neutral conditions. Extremes in pH levels can denature the enzyme and reduce its activity.


Which genetic mutation results in nonfunctioning melanocytes that do not produce melanin?

The genetic mutation that results in nonfunctioning melanocytes, which do not produce melanin, is typically associated with the condition known as albinism. Specifically, mutations in the TYR gene, which encodes the enzyme tyrosinase, are often responsible for this lack of melanin production. Tyrosinase is crucial for the synthesis of melanin, and its absence leads to the characteristic hypopigmentation seen in individuals with albinism.


What is the missing protein that makes people albino?

The missing protein in people with albinism is called tyrosinase. Tyrosinase is an enzyme that plays a key role in the production of melanin, the pigment that gives color to the skin, hair, and eyes. Its absence or low activity in individuals with albinism leads to a lack of melanin production, resulting in their characteristic pale skin, hair, and eyes.

What seems to produce more melanin pigmentation in the extremities of Siamese cats?

Albinism is a mutation in the TYR gene, responsible for the enzyme tyrosinase. Tyrosinase, in turn, is necessary for the production of melanin, or dark pigmentation.See the related link for further information.

Which cat represents a coat pattern that is regulated by temperature?

The Siamese cat has temperature-sensitive pigment expression due to the albino gene. The coat pattern is a result of this gene because it is a defective form of tyrosinase that is regulated by the cat's body temperature.


What gene causes albinism?

Ocular albinism (OA1) is caused by a genetic defect on chromosome 11 of the GPR143 gene. Oculocutaneous albinism type 2 (OCA2 or P gene albinism) results from a genetic defect on chromosome 15 in the P protein that helps the tyrosinase enzyme to function. Oculocutaneous albinism type 3 (OCA3) is rarely described and results from a genetic defect on chromosome 9 in TYRP1, a protein related to tyrosinase. Oculocutaneous albinism type 4 (OCA4) results from a genetic defect in chromosome 5 at position 13.3, in the SLC45A2 protein that helps the tyrosinase enzyme to function.
