The structure of inducing factors for virginiamycin production in Streptomyces virginiae.
Virginiamycin inducing factors (inducing material or inducing factor) of Streptomyces virginiae were isolated from the culture broth of this microbe and separated into three closely related compounds. They were named virginiae butanolides A, B and C and their structures were determined as 2-(1'-hydroxy-5'-methylhexyl)-3-(hydroxymethyl)butanolide (6), 2-(1'-hydroxy-4'-methylhexyl)-3-(hydroxymeth...
متن کاملStreptomyces spadicogriseus, a new species producing anthramycin.
The taxonomic description of Streptomyces spadicogriseus, a new species belonging to the Gray Series of streptomycetes as classified by Pridham and Tresner, is presented. This new species is distinguishable from the known members of the Gray Series. Streptomyces spadicogriseus produces anthramycin but bears no taxonomic relation to the known producer of the antibiotic: S. refuineus var. thermot...
متن کاملNew antitumor antibiotic, FR-900462. I. Taxonomy of the producing strain.
A new species of the genus Streptomyces, the proposed name of which is Streptomyces tokashikiensis sp. nov., is described. Soil isolate, strain No. 7124, produces a new antitumor antibiotic FR-900462. The organism is characterized by the presence of spores on the substrate hyphae. Strain No. 7124 is closely related to Streptomyces spiralis in morphological and cultural characteristics, but ther...
متن کاملStreptogramin B biosynthesis in Streptomyces pristinaespiralis and Streptomyces virginiae: molecular characterization of the last structural peptide synthetase gene.
Streptomyces pristinaespiralis and S. virginiae both produce closely related hexadepsipeptide antibiotics of the streptogramin B family. Pristinamycins I and virginiamycins S differ only in the fifth incorporated precursor, di(mono)methylated amine and phenylalanine, respectively. By using degenerate oligonucleotide probes derived from internal sequences of the purified S. pristinaespiralis Snb...

Introduction: Streptomyces species are mycelial, aerobic gram-positive bacteria that are isolated from soil and produce a diverse range of antibiotics. Streptomyces griseus produces the antibiotic, streptomycin and forms spores even in a liquid culture. The gene cluster for the production of Streptomycin antibiotic contains strR gene that encodes StrR, a pathway-specific regulator. Then, this p...
