| 摘要 |
The present invention provides a novel expression system for the production of protein in bacterial hosts. The system utilizes novel promoters that are highly efficient in initializing transcription and therefore enhance protein yield. The promoters comprise the -35 region of the consensus E. coli promoter, the -10 region of the IppP-5 promoter and a spacer between these two regions derived from either the Ipp or IacUV5 promoters.
