title: A mutation in Salmonella typhimurium imparting conditional resistance to 5-fluorouracil and a bioenergetic defect: mapping of cad.
abstract: The position of the genetic locus allelic with the cad-2 mutation has been located between units 14 and 15 of the linkage map of S. typhimurium. Fine structure mapping established the gene order as cad flrB nag. The genetic evidence coupled with biochemical evidence indicates that this cad locus is homologous to the ubiF gene of Escherichia coli.
