    摘要: A method locating insertion elements (IS elements) or transposons in coryneform bacteria, a positive selection system suitable for the above, the IS elements found in this manner and their use, is disclosed. The method involves:(1) The construction of a non-self-transferrable vector mobilizable from an E. coli mobilizer strain which vector is composed of(a) A DNA segment containing a replicon functional in E. coli,(b) A second DNA segment containing the DNA fragment coding for the mobilization function (Mob site containing the oriT),(c) A third DNA segment which recombines homologously in Gram-positive bacteria and/or contains a replicon functional in coryneform bacteria,(d) A DNA segment from Bacillus subtilis containing the sacB gens,(2) Transfer of this vector by means of conjugative transfer into the coryneform recipient strains,(3) Cultivation of the transconjugants containing the vector in an .about.10% sucrose-containing nutrient medium,(4) Lysis of the sucrose-resistant clones, cleaving of the plasmids with restriction endonucleases and analysis of the fragments.

    摘要: S. ghanaensis DSM 2932 is resistant to gentamicin at up to 20 .mu.g/ml. Total digestion of the genomic DNA with BglII, incorporation of the restriction fragments into a suitable plasmid, and selection using gentamicin results in gentamicin-resistant clones which contain a 7 kb fragment with the gentamicin-resistance gene. The plasmid pPH1JI likewise contains a gentamicin-resistance gene located on a 2.3 kb HindIII-BamHI fragment. These genes are suitable as markers, in particular for Streptomycetes vectors.
