Abstract	DNA replication initiation in prokaryotes and eukaryotes requires the recruitment and loading of a helicase at the replication origin. To subsequently unwind the double-stranded DNA, the helicase must be properly positioned on the separated DNA strands. Several studies have revealed similarities and differences in the mechanisms used by different autonomously replicating DNA elements (replicons) for recruitment and activation of the appropriate helicase. Of particular interest are plasmid replicons that are adapted for replication in diverse bacterial hosts and are therefore intriguingly able to exploit the helicases of distantly related bacterial species. The different molecular mechanisms by which replicons recruit and load helicases are only just beginning to be understood.
