WebTyrosinase is a copper -containing enzyme present in plant and animal tissues that catalyzes the production of melanin and other pigments from tyrosine by oxidation. It is found inside melanosomes which are synthesized in the skin melanocytes. In humans, the tyrosinase enzyme is encoded by the TYR gene. [6] Catalyzed reaction [ edit] WebA number of introns as large as 100 kbp and larger are known in, for example, humans ( Nobile et al. 1997; Bärlund et al. 2002) but we did not wish to include such introns in our data set without manual confirmation of each such alignment. Such extremely large introns were extremely rare in our data set.
