| Abstract: | A Salmonella typhimurium LT2 cosmid library was constructed, and a 46-kb recombinant plasmid was isolated that could complement an Escherichia coli rha mutant. Subsequent subcloning generated a 13.6-kb ClaI restriction fragment that contained a functional regulatory element. By complementation analyses using different subclones, the approximate physical locations of rhaT, rhaC1, rhaC2, rhaB, rhaA, and rhaD were determined. The nucleotide sequence spanning the rhaB and rhaC2 genes was determined. |
