Uracil uptake in Escherichia coli K-12: isolation of uraA mutants and cloning of the gene.

Journal of bacteriology - 1 Apr 1995

Abstract excerpt

Mutants defective in utilization of uracil at low concentrations have been isolated and characterized. The mutations in question (uraA) map close to the upp gene encoding uracil phosphoribosyltransferase. By complementation analysis, a plasmid that complements the uraA mutation has been isolated. The uraA gene was shown to be the second gene in a bicistronic operon with upp as the promoter proximal gene. The...
