Gregory, Kenneth F. (Ontario Agricultural College, Guelph, Ontario, Canada), and Jay C. C. Huang. Tyrosinase inheritance in Streptomyces scabies. II. Induction of tyrosinase deficiency by acridine dyes. J. Bacteriol. 87:1287-1294. 1964.-Growth in minimal medium containing 1 mug of acriflavine per ml resulted in a large increase (up to 62%) in the frequency of tyrosinase-deficient (tye(-)) mutan...
متن کاملGenetic recombination in Streptomyces griseus.
Low-frequency (10(-6)) genetic recombination was observed in a cephamycin-producing strain of Streptomyces griseus. The recombinants were predominantly heteroclones. Heteroclone analysis was performed involving four heteroclones of one cross. In 100 mutants correlation was found between the type of auxotrophy and the level of antibiotic activity. A cross of this strain with a streptomycin-produ...
متن کاملGenetic Recombination in Crosses Between Streptomyces aureofaciens and Streptomyces rimosus.
Polsinelli, M. (University of Pavia, Pavia, Italy), and Maria Beretta. Genetic recombination in crosses between Streptomyces aureofaciens and Streptomyces rimosus. J. Bacteriol. 91:63-68. 1966.-Biochemical mutants were obtained from Streptomyces rimosus and S. aureofaciens by ultraviolet irradiation. Crosses were performed between auxotrophic strains of S. rimosus and S. aureofaciens with posit...
متن کاملAlbino mutants of Streptomyces glaucescens tyrosinase.
Site-directed mutagenesis was used to determine the functional role of several residues of Streptomyces glaucescens tyrosinase. Replacement of His-37, -53, -193 or -215 by glutamine yields albino phenotypes, as determined by expression on melanin-indicator plates. The purified mutant proteins display no detectable oxy-enzyme and increased Cu lability at the binuclear active site. The carbonyl d...
متن کاملStreptomyces Tyrosinase: Production and Practical Applications
Tyrosinases (monophenol, o-diphenol:oxygen oxidoreductase, EC (1.14.18.1) are copper-containg enzymes which catalyze the o-hydroxylation of monophenols and subsequent oxidation of o-diphenols to quinones. The enzymes are involved in the pigmentation and are important factors in wound healing and primary immune response. Tyrosinases are found in prokaryotic and eukaryotic microorganisms, in mamm...
