Abstract excerpt

We have developed a genetic system with which to replace oriC+ on the Escherichia coli chromosome with modified oriC sequences constructed on plasmids. Using this system we have demonstrated that chromosomal oriC can tolerate the insertion of a 2 kb fragment at the HindIII site between DnaA boxes R3 and R4, whereas the same insertion completely inactivates cloned oriC. We have further found that although R4 is...
