Main Points of the Paper
Please summarize the main points of the paper.
- Characterization of 4 isolated putative promoter mutants that severely reduce the maximum rate of expression of the lac operon
- L1-small deletion which removes part of the promoter and an adjacent segment of the i gene
- L8- transitional point mutation
- L37-transitional point mutation
- L29-transitional point mutation
- L8 and L37 are repeats of the same mutation.
