TYR, Human (HEK293, His)

TYR protein, a copper-containing oxidase, initiates melanin production by catalyzing the hydroxylation of tyrosine to DOPA. This essential step is rate-limiting in the synthesis of melanins and polyphenolic compounds. TYR further enables the oxidation of DOPA to DOPA-quinone and potentially mediates the conversion of DHI to indole-5,6 quinone, playing a crucial role in the intricate cascade of reactions involved in melanin biosynthesis. TYR Protein, Human (HEK293, His) is the recombinant human-derived TYR protein, expressed by HEK293 , with N-6*His labeled tag.
