WebGenetically Engineered Salmonella Typhimurium for Targeting & Selective Expression of TRAIL in Necrotizing Tumors WebThe primary attachment site, ataA, for phage P22 in S. typhimurium is located between the genes proA,B and supQ newD. (The newD gene is a substitute gene for the leuD gene, restoring leucine prototrophy of leuD mutant strains.) The proA,B and supQ newD genes are very closely linked and thus cotransducible by generalized transducing particles.
