1. Claims (for the Contracting States : BE, CH, DE, FR, GB, IT, LI, LU, NL and SE) A synthetic regulation region for the expression of heterologous genes in E. coli, containing a promotor, a modified lac operator and a ribosome-binding site, characterized in that a) the -35 region in the promotor has the nucleotide sequence (coding strand) TTGACAT or CTTGACAT b) the -10 region in the promotor has the nucleotide sequence (coding strand) GTATAAT, c) a spacer group of 14 to 17 base-pairs is between the -35 and the -10 regions, and d) a spacer group of 6 to 14 base-pairs is located between the ribosome-binding site and the ATG start codon. 1. Claims (for the Contracting State AT) A process for the expression of heterologous genes in E. coli, characterized by placing, upstream of the heterologous gene in the direction of reading, a synthetic regulation region which contains a promotor, a modified lac operator and a ribosome-binding site, in which a) the -35 region in the promotor has the nucleotide sequence (coding strand) TTGACAT or CTTGACAT b) the -10 region in the promotor has the nucleotide sequence (coding strand) GTATAAT, c) a spacer group of 14 to 17 base-pairs is between the -35 and the -10 regions, and d) a spacer group of 6 to 14 base-pairs is located between the ribosome-binding site and the ATG start codon. |
