| 摘要 |
The invention is a process for controlling the expression of heterologous genes from lac-operated promoters by removing the CAP binding site and lac promoter from the lac operon. Illustrated is the fusion of the lacZ, Y, and A genes of the lac operon to the 3 min end of the lacI structural gene. This elimination of the natural regulatory elements of the lac operon results, advantageously, in the production of lac operon gene products in a constitutive mode from the lacI promoter. |
