Claims
- 1. A DNA sequence comprising a hybrid yeast promoter fused to a heterologous gene, said hybrid yeast promoter comprising an ENO2 promoter, wherein said ENO2 promoter includes the upstream activating sequence and TATA region naturally associated with said ENO2 promoter, and an additional upstream activating sequence derived from a yeast promoter operably fused to said ENO2 promoter, wherein said additional upstream activating sequence is located between said ENO2 upstream activating sequence and TATA region.
- 2. The DNA sequence of claim 1 wherein said additional upstream activating sequence is derived from a yeast promoter other than said ENO2 promoter.
- 3. The DNA sequence of claim 1 wherein said additional upstream activating sequence is derived from an ENO2 promoter.
- 4. The DNA sequence of claim 1, wherein said additional upstream activating sequence is a GAL1,10 upstream activating sequence having a GAL1-proximal end and a GAL10-proximal end.
- 5. The DNA sequence of claim 4, wherein said GAL1-proximal end is closest to said heterologous gene.
- 6. The DNA sequence of claim 4, wherein said GAL10-proximal end is closest to said heterologous gene.
- 7. The DNA sequence of claim 4, wherein said GAL1,10 upstream activating sequence is derived from the GAL1,10 DNA sequence of yeast of the genus Saccharomyces.
- 8. The DNA sequence of claim 7, wherein said yeast is S. cerevisiae.
- 9. A yeast cell transformed with the DNA sequence of claim 1.
- 10. The yeast cell of claim 9, wherein yeast is of the genus Saccharomyces.
- 11. A plasmid vector comprising the DNA sequence of claim 1, wherein said vector is capable of transforming a host yeast cell.
- 12. The DNA sequence of claim 1, wherein said heterologous gene encodes a glucoamylase.
- 13. The vector pSV30.
- 14. The vector pSV31.
- 15. A method of producing a protein other than enolase 2 comprising growing a yeast cell transformed with a vector of claim 11.
