ID 1.11.2.6 DE L-tyrosine peroxygenase. CA H2O2 + L-tyrosine = H2O + L-dopa. 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. //
