WebStbA protein is a DNA-binding protein (identical to ParM) and is strictly required for the stability and intracellular positioning of plasmid R388 in E. coli. StbA binds a cis -acting sequence, the stbDRs. The StbA- stbDRs complex may be used to pair plasmid the host chromosome, using indirectly the bacterial partitioning system.
