CC   -!- FUNCTION: This protein is essential for plasmid replication; it is
CC       involved in copy control functions. In vitro, binds to the DNA repeat
CC       units, BCDD'D'', EFG and HIJ (By similarity). {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the initiator RepB protein family.
CC       {ECO:0000305}.
