tyrosinase is requied for ripening of fruit? no..it's it's only the browning of fruit that tyrosine is responsible for...

Duplicate article. Tyrosinase is the same thing as Tyrosine Hydroxylase

edit

We have two separate articles on Tyrosinase and Tyrosine Hydroxylase Dflyer (talk) 14:53, 20 April 2015 (UTC) — Preceding unsigned comment added by Dflyer (talkcontribs) 19:24, 19 April 2015 (UTC)Reply

The origin of the word 'tyrosinase'

edit

From the article:

A German scientist named Albert Rugerstein named this enzyme Tyrosinase after his friend, Tyro Sinaster. Tyro means to be an inexperienced person; beginner.

Is this true? In the tyrosine article appears this contradictory, and more plausible, statement:

Tyrosine (from the Greek tyros, meaning cheese, as it was first discovered in 1846 by German chemist Justus von Liebig in cheese[1][2]) ...

albinism, disease or disorder?

edit

Perhaps it is a distinction without a difference, but Disorder seems more appropriate (see albinism Dbrodbeck (talk) 22:06, 12 May 2010 (UTC)Reply

Albinism is a phenotype. It is not a disease or a disorder. It is merely a lack of pigmentation, and any disease or disorder resulting from it is not albinism. Mdsk (talk) 07:27, 7 March 2011 (UTC)Reply

So definitely not disease then.... I actually have no problem with the word disorder, or actually disease, I just want consistency. Dbrodbeck (talk) 12:44, 7 March 2011 (UTC)Reply
Well usually albinism (as in oculocutaneous albinism type I) is called a "rare disease", and it is considered to cause low vision. But this is not so simple, as a trait it is not easily understood as a disease. --146.211.0.10 (talk) 13:11, 6 September 2017 (UTC)Reply

plant sources?

edit

It would be good to know if there are any plant sources of this enzyme seeing as adding copper, tyrosine, and tyrosinase to ones diet seems to be something of a solution to grey hair. Havabighed (talk) 06:43, 5 July 2012 (UTC)Reply

Significance in food industry

edit

I'm concerned that the abstract of the paper referenced for the comments on vanillic acid, vanillin, and vanillic alcohol actually mentions "two chemicals, isovanillin ... isovanillyl alcohol" which are not the same things at all. I don't have access to the full text (it's pay-per-view)... so it would be reassuring if someone who does can confirm that the paper does agree with what's written in the Wikipedia article. At the moment this looks like an error; indeed, according to http://ir.cnu.edu.tw/retrieve/44271/99_3_j.pdf (to which I do have access) quote "Vanillin did not express inhibition of tyrosinase activity."

Tyrosine to dopaquinone

edit

The following should be included: Tyrosinase has two activities, conversion from tyrosine to dopaquinone directly, and oxidation of catechols to o-quinones. See for example "Sugumaran, Manickam, and Hanine Barek. "Critical analysis of the melanogenic pathway in insects and higher animals." International Journal of Molecular Sciences 17.10 (2016): 1753." --146.211.0.10 (talk) 13:20, 6 September 2017 (UTC)Reply
