Abstract excerpt

The effects of mutations in the promoter of the histidine operon of Salmonella typhimurium were examined in vivo. The wild-type chromosomal copy of the his promoter was replaced with mutations in the -10 hexamer sequence and in the region between the -10 hexamer and the transcriptional start poin...
