Mutation in the phosphoribosylpyrophosphate synthetase gene (prs) that results in simultaneous requirements for purine and pyrimidine nucleosides, nicotinamide nucleotide, histidine, and tryptophan in Escherichia coli.
A mutant of Escherichia coli harboring a temperature-labile phosphoribosylpyrophosphate (PRPP) synthetase was characterized. Despite the lack of a detectable PRPP pool or PRPP synthetase activity at 40 degrees C, the strain was fully viable at this temperature as long as guanosine, uridine, histidin...
