Title 10Sa RNA complements the temperature-sensitive phenotype caused by a mutation in the phosphoribosyl pyrophosphate synthetase (prs) gene in Escherichia coli.
Journal Genes Genet Syst
Abstract From Escherichia coli cells with a deletion in the ssrA gene that encodes 10Sa RNA after treatment with a mutagen, we isolated two temperature-sensitive mutants, which we designated TS15 and TS101. The temperature-sensitive (ts) phenotype of the mutants could be overcome by introduction of the wild-type ssrA gene but not by the mutants of ssrA. By a complementation test using Kohara's mini-set of clones and by subcloning of a fragment from the phage clone 246, we found that both mutations were in the prs gene that encodes phosphoribosyl pyrophosphate synthetase. Sequencing of the mutant prs gene of TS101 showed that residues 215, cysteine, in the encoded protein had been changed to tyrosine. That such a mutant exists suggests that 10Sa RNA associate with the prs gene product in a functional way.
