WebUnwinding of these three DUEs is a necessary step for DNA replication to initiate. The distant pull from duplex melting at the DnaA box sequence is what induces further melting at the M and R DUE sites. The more distant L site is then unwound by DnaB binding. Unwinding of these 13-mer sites is independent of oriC-binding proteins.
