Tyrosinase; part of the gene cluster that mediates the biosynthesis of Asp-melanin, a pigment that confers resistance against UV light and hampers phagocytosis by soil amoeba (PubMed:27133313, PubMed:29270299). The nonribosomal peptide synthase melA converts 4-hydroxyphenylpyruvate (4-HPPA) to aspulvinone E (PubMed:27133313, PubMed:29270299). The tyrosinase tyrP then performs hydroxylations of both aromatic moieties of aspulvinone E (PubMed:27133313). The product of tyrP is highly unstable, and, due to the high reactivity of methides and ortho-diquinones, the polymeric Asp-melanin forms spontaneously (PubMed:27133313). Binds 2 copper ions per subunit. Activity is inhibited by the presence of dithiothreitol (DTT). Optimum pH is 5-7. The oxidizing environment of Golgi or endoplasmic reticulum (ER) is required for tyrP to be active. Expression is induced during conidiation. Glycosylated. Results in yellow fluorescent conidia and accumulates aspulvinone E in conidia. Belongs to the tyrosinase family.
