## Abstract The genes for the wellβcharacterized highβaffinity histidine transport system of S typhimurium have been cloned in Ξ»gt4. Genetic and physiological analyses of the analogous transport system of E coli were undertaken in order that available Ξ» vectors, recombinant DNA techniques, and a ge

Experiments are performed to compare the mutagenic properties of the three phosphamide esters of nitrogen mustard, cyclophosphamide (CP), ifosfamide (IF), and trofosfamide (TF), in different bacterial systems. The systems include forward mutations leading to resistance against 5-methyltryptophan (MT
