title: Gentic mapping of Salmonella typhimurium peptidase mutations.
abstract: The map positions of three loci, each specifying a different peptidase, have been determined in Salmonella typhimurium. Mutations in pepN (leading to loss of peptidase N [1974] are co-transducible with pyrD. The order of markers in this region is put pyrD pepN. Mutations in pepA (leading to loss of peptidase A [1974] are co-transducible with pyrB and argI. The relative orientation of these markers is pepA argI pyrB. Mutations in pepDP (leading to loss of dipeptidase, peptidase D) are co-transducible with proBA and gxu. The order of these markers is pepD gxu pro.
