pyrR identical to pyrH in Salmonella typhimurium: control of expression of the pyr genes.

Abstract

Mutants of Salmonella typhimurium showing constitutive synthesis of the pyrimidine biosynthetic enzymes coded for by the pyrA-F genes (G. A. O'Donavan and J. C. Gerhart, 1972) have been reinvestigated. The high rate of expression of the pyrB-F genes in these mutants as well as their pyrimidine excretion is shown to be due to mutations in the gene pyrH encoding uridine 5'-monophosphate kinase. Thus, the term pyrR used for these mutants should be replaced by the designation pyrH.
