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.

Materials and Methods Used

Please list the materials and methods used in this paper (strains, plasmids, antibodies, etc).
