background the search for novel antibiotics continues to be of immense importance in research programs around the world for pharmaceutical, industrial and agricultural applications. filamentous soil bacteria, belonging to the streptomyces genus, are widely used as an important biological tool for their ability to produce a wide range of novel secondary metabolites, such as “antibiotics”. object...
A Gram-stain-positive actinobacterium, designated strain YIM DR4008, was isolated from the root sample of Psammosilene tunicoides collected from Lijiang, Yunnan, China. Strain YIM DR4008 could grow at temperatures ranging from 10 to 50 C (optimum 28–30 C), at pH 5.0–11.0 (optimum pH 7.0) and in the presence of up to 4% (w/v) NaCl. Sequence analysis of the 16S ribosomal RNA gene revealed that st...
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...
