This protein is an initiator of plasmid replication [1-6]. RepB possesses nicking-closing (topoisomerase I) like activity. It is also able to perform a strand transfer reaction on ssDNA that contains its target. This entry also includes RepA which is an E.coli protein involved in plasmid replication. The RepA protein binds to DNA repeats that flank the repA gene [3,4]. These proteins consist of two domains containing a winged helix-turn-helix motif, the N-terminal one, WH1, represented in this entry, is involved in the dimerization of RepE and an auxiliary binding to DNA. The C-terminal one, WH2, is related to a sequence-specific binding to the common 8 bp of the iteron [6].	Domain
