The single replicator 245 bp required for E. coli chromosomal replication is called oriC. Two repeated motifs are critical for oriC function.

The 9-mer motif is the binding site for the E. coli initiator, DnaA, and is repeated five times at oriC.

The 13-mer motif, repeated three times, is the initial site of ssDNA formation during initiation.
