The replication terminus region of the E. coli chromosome encodes a locus, dif, that is required for normal chromosome segregation at cell division, dif is a substrate for site-specific recombination catalysed by the related chromosomally encoded recombinases XerC and XerD. (gla.ac.uk)
It is shown that the only DNA sequences required for wild-type dif function in the terminus region of the chromosome are contained within 33 bp known to bind XerC and XerD, and that certain active site residues of the Xer proteins known to be involved in the catalysis of recombination are required for normal chromosome segregation. (gla.ac.uk)
Since neither the dif/Xer, nor the loxP/Cie system caused this suppression when located in other positions on the chromosome, close to oriC or within lacZ, this reinforces the idea that site-specific recombination must occur in the terminus region in order to allow normal chromosome segregation. (gla.ac.uk)
