Abstract excerpt
The SopA protein plays an essential, though so far undefined, role in partition of the mini-F plasmid but, when overproduced, it causes loss of mini-F from growing cells. Our investigation of this phenomenon has revealed that excess SopA protein reduces the linking number of mini-F. It appears to do so by disturbing the partition complex, in which SopB normally introduces local positive supercoiling upon binding...
