Locations of the opp and supX genes of Salmonella typhimurium and Escherichia coli.

AUTOR(ES)
RESUMO

The chromosomal locations of the supX and opp loci of Salmonella typhimurium LT2 and Escherichia coli K-12 were identified and found to result in the same gene sequence in both species, namely, pyrF-cysB-supX-trpPOLEDCBA-tonB(chr)-opp. These results differ from a previously reported location of the opp gene on the E. coli chromosome. Evidence indicates that the opp gene lies between chr(tonB) and galU in S. typhimurium.
