The right junction direct repeat sequence (DR-R) was previously shown to be identical to the sequence from the respective thdf sequences from sensitive serovar Typhimurium or Agona strains, suggesting the origin of the DR-R is actually the end of thdF (Figure 2) (6).
The right junction 18-bp DR-R direct repeat sequence found at the 3' end of SGI1 appears to be a duplication of the last 18 bp of the thdf gene found upstream of SGI1.
