Protoplast Regeneration and Transformation of Thiostrepton-Producing Streptomyces Zaurentii ATCC 31255
نویسندگان
چکیده
The optimum condition for the protoplast formation and regeneration of S(yeptomyces Laurentii ATCC 31255 was studied. The effective formation and regeneration of protoplasts were obtained by using the mycelia grown to the stationary phase in the presence of 0.4% glycine, and by treatment with 1 mg/ml of lysozyme in PWP buffer. When plasmids, pMCP5 and its derivative pYK3 (smaller in size) having a kanamycin resistance gene, were transformed into the protoplasts by using 20% (V/V) PEG 2000 in PWP buffer, the high number of transformants were obtained at a frequency of 4.3 x lo5 and 3.4 x lo4 per pg DNA of pMCP5 and pYK3, respectively.

متن کاملGenetic Recombination and Transformation in Protoplasts of Thermomonospora fusca.
Protoplasts were produced from the thermophilic actinomycete Thermomonospora fusca and were regenerated to 0.1% of the direct count on regeneration agar. Recombination after protoplast fusion was demonstrated with drug-resistant mutants of T. fusca YX. A single thiostrepton-resistant colony was isolated after transformation of T. fusca YX with the streptomycete vector pIJ702, providing the firs...
متن کاملHeterologous production of thiostrepton A and biosynthetic engineering of thiostrepton analogs.
Thiostrepton A 1, produced by Streptomyces laurentii ATCC 31255 (S. laurentii), is one of the more well-recognized thiopeptide metabolites. Thiostrepton A 1 and other thiopeptides are of great interest due to their potent activities against emerging antibiotic-resistant Gram-positive pathogens. Although numerous lines of evidence have established that the thiopeptides arise from the post-transl...
متن کاملReplacement of Streptomyces hygroscopicus genomic segments with in vitro altered DNA sequences.
We have developed a method for gene replacement in Streptomyces hygroscopicus which permits introduction of an in vitro derived mutation carried on a plasmid into the chromosome. We constructed the plasmid pMSB212 which can replicate in S. hygroscopicus and contains the step5 gene of the bialaphos biosynthetic pathway which was inactivated by a frame-shift mutation caused by filling in the cohe...
