[Chemico-enzymatic synthesis of genetic elements for expression of synthetic genes in Bacillus subtilis cells].

In order to obtain the recombinant Bacillus subtilis strain, a transcriptional-translational control unit of the alpha-amylase gene of B. amyloliquefaciens was synthesized. The oligodeoxyribonucleotides were prepared by the modified triester method in solution and by the solid-phase approach. Then these oligonucleotides were joined by DNA ligase into two fragments which were cloned in the phage M13mp9 DNA and the plasmid pBR327. A plasmid harboring the site regulating the transcription of the alpha-amylase gene may be employed as vector for cloning the promoter-containing fragments in E. coli cells.
