The P1 partition region contains two large open reading frames that encode the proteins ParA and ParB. It was previously shown that ParA is essential for partition activity. Using a novel assay, we show that ParB protein is also an absolute requirement for partition and that it is active in trans to the partitioning plasmid. Development of complementation… CONTINUE READING
