Molecular analysis of the rfaD gene, for heptose synthesis, and the rfaF gene, for heptose transfer, in lipopolysaccharide synthesis in Salmonella typhimurium. J Bacteriol. 1994;176:2379-85 pubmed..coli K-12 is about 35%, much lower than the average of enteric bacteria; if this low G+C content is due to lateral transfer from a source of low G+C content, it must have occurred prior to evolutionary divergence of the two genera. ..

The assembly system for the lipopolysaccharide R2 core-type of Escherichia coli is a hybrid of those found in Escherichia coli K-12 and Salmonella enterica. Structure and function of the R2 WaaK and WaaL homologs. J Biol Chem. 1998;273:8849-59 pubmed..coli K-12. However, the products of waaK (rfaK) and waaL (rfaL) each resemble homologs in Salmonella enterica serovar Typhimurium but share little similarity with E. coli K-12...
