physiological function |
Salmonella serogroup polymorphism based on abequose and paratose arose by divergence from an ancestral gene to give abequose and paratose synthase in different strains or species, and this happened in a bacterial group with low G+C content. Later a recombination event brought either paratose synthase gene rfbS or abeqouse synthase gene rJbJ into the genetic background of the other. These events were followed by one form being picked up by a Salmonella strain and becoming adapted to put a dideoxyhexose into its own 0-antigen |
