Abstract
The present invention provides regulatory polynucleotide molecules isolated from a 16S rDNA for enhanced expression of heterologous genes. The invention further discloses compositions, polynucleotide constructs, transformed host cells containing the regulatory polynucleotide sequences, and methods for preparing and using the same.
Claims10
A transgenic prokaryotic cell comprising a polynucleotide molecule comprising a 16S rDNA promoter molecule operably linked to a nucleic acid comprising a heterologous ribosomal binding site, wherein the polynucleotide molecule has promoter activity, and wherein the 16S rDNA promoter molecule is isolated from a prokaryote, wherein the polynucleotide comprises a sequence selected from the group consisting of:
- a) a nucleic acid sequence comprising SEQ ID NO:7;
- b) a nucleic acid sequence comprising at least 85% sequence identity to SEQ ID NO:7;
- and
- c) a fragment of the nucleic acid sequence of SEQ ID NO:7.
A transgenic prokaryotic cell comprising polynucleotide molecule comprising a 16S rDNA promoter molecule operably linked to a nucleic acid comprising a heterologous ribosomal binding site, wherein the polynucleotide molecule has promoter activity, and wherein the 16S rDNA promoter molecule is isolated from a prokaryote, wherein the ribosomal binding site is isolated from the Agrobacterium virE operon.
