A Mutant of Escherichia coli with a New, Highly Efficient Promoter for the Lactose Operon

Jeremy Bruenn 1, Helen Hollingsworth 1
PMCID: PMC427308  PMID: 4590169

Abstract

We have isolated a mutant of E. coli whose maximal rate of synthesis of lac mRNA is 25-fold greater than that of its parental wild-type strain. The mutant also shows alterations in the kinetics of β-galactosidase synthesis, the functional half-life of β-galactosidase mRNA, and the properties of lac repressor.

Keywords: transcription, lac mRNA, competition hybridization
