ID 1.11.2.6 DE L-tyrosine peroxygenase. CA L-tyrosine + H2O2 = L-dopa + H2O. CC -!- The enzyme from the bacterium Streptomyces lincolnensis participates CC in the biosynthesis of the antibiotic lincomycin A, while that from CC Streptomyces refuineus is involved in anthramycin biosynthesis. CC -!- The enzyme, which contains a heme b cofactor, is rapidly inactivated CC in the presence of hydrogen peroxide, but the presence of L-tyrosine CC protects it. cf. EC 1.11.2.5. //
