Genetic 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 کاملOxidation of Meloxicam by Streptomyces griseus
The aim of the present investigation was to biotransform the anti-inflammatory compound meloxicam by enzymes present in whole cells of five actinomycete cultures to produce novel bioactive derivatives. Among the actinomycetes screened, Streptomyces griseus NCIM 2622 was found to possess the enzyme system(s) that oxidize meloxicam into two metabolites whereas that present in S. griseus NCIM 2623...
متن کاملComplete nucleotide sequence of a 16S ribosomal RNA gene from Streptomyces griseus subsp. griseus.
The complete nucleotide sequence of the 1525 bp 16S ribosomal RNA gene from the rrnE operon of Streptomyces griseus subsp. griseus KCTC9080 was determined (1). The 5' and 3' ends of the 16S rRNA were located with the combination of previous data (2,3,4) and have not been determined experimentally. The nucleotide sequence presented here was determined following the dideoxy method (5) and using M...
متن کاملAmfS, an extracellular peptidic morphogen in Streptomyces griseus.
The amf gene cluster was previously identified as a regulator for the onset of aerial-mycelium formation in Streptomyces griseus. The nucleotide sequences of amf and its counterparts in other species revealed a conserved gene organization consisting of five open reading frames. A nonsense mutation in amfS, encoding a 43-amino-acid peptide, caused significant blocking of aerial-mycelium formatio...
متن کاملSelf-cloning in Streptomyces griseus of an str gene cluster for streptomycin biosynthesis and streptomycin resistance.
An str gene cluster containing at least four genes (strR, strA, strB, and strC) involved in streptomycin biosynthesis or streptomycin resistance or both was self-cloned in Streptomyces griseus by using plasmid pOA154. The strA gene was verified to encode streptomycin 6-phosphotransferase, a streptomycin resistance factor in S. griseus, by examining the gene product expressed in Escherichia coli...
