A Mutant Allele of rpoD Results in Increased Conversion of Aminoimidazole Ribotide to Hydroxymethyl Pyrimidine in Salmonella enterica

Department of Bacteriology, University of Wisconsin—Madison, Madison, Wisconsin

Received 14 January 2004/ Accepted 16 March 2004

An allele of rpoD (rpoD1181) that results in increased synthesis of the pyrimidine moiety of thiamine in Salmonella enterica was identified. The S508Y substitution caused by rpoD1181 is analogous to the S506F derivative of the Escherichia coli protein. The properties of this E. coli mutant protein have been well characterized in vitro. Identification of a metabolic phenotype caused by the rpoD1181 allele of S. enterica allows past in vitro results to be incorporated in continuing efforts to understand cellular processes that are integrated with the thiamine biosynthetic pathway.
