Mutations in the araC gene of Escherichia coli B/r were isolated which alter both activation of the araBAD operon expression and autoregulation. The mutations were isolated on an araC-containing...
Functional limits of the araIc promoter suggest an additional regulatory site for araBAD expression.
Horwitz, A H, Miyada, C G, Wilcox, G
The araBAD promoter is defined, in part, by two types of cis-acting constitutive mutations, araIc at position -35 and araXc at position -10. Subcloning experiments demonstrated that the araIc and...
Genetic characterization of Salmonella typhimurium LT2 ara mutations.
