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
The origin of the word 'tyrosinase'
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) ...

albinism, disease or disorder?
- 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)
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)
Significance in food industry
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
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." --184.108.40.206 (talk) 13:20, 6 September 2017 (UTC)
