Salmonella typhimurium histidine periplasmic permease mutations that allow transport in the absence of histidine-binding proteins.

Abstract excerpt

Periplasmic transport systems consist of a membrane-bound complex and a periplasmic substrate-binding protein and are postulated to function by translocating the substrate either through a nonspecific pore or through specific binding sites located in the membrane complex. We have isolated mutants carrying mutations in one of the membrane-bound components of the histidine permease of Salmonella typhimurium that...
