A Mutant of <i>Escherichia coli</i> with a New, Highly Efficient Promoter for the Lactose Operon is a research paper published in Proceedings of the National Academy of Sciences (1973). On theSindex it has a DataRank of 0.559. It has been cited 10 times, with 8 citing works in its 1-hop citation network.
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.
