Experimental promoter identification of a representative food-borne pathogen Salmonella enterica serovar Typhimurium LT2 with near single base-pair resolution
RpoD is a houskeeping sigma factor and RpoN is an alternative one. It was identified their intragenic and intergenic binding sites and association with the RNA polymerase. Overall design: The bacteria were grown up to mid-log phase, cultured in M9 minimal media with 0.2% glucose.  The experiments were conducted in biological duplicate.
