Deoxyribonucleic acid and outer membrane: binding to outer membrane involves a specific protein.
The binding of deoxyribonucleic acid (DNA) to the outer membrane of Escherichia coli was examined. The amount of DNA found to be bound to outer membrane was low and was estimated to be about 0.4% of the total DNA. Treatment of cells with chloramphenicol or rifampin caused a disassociation of the apparent DNA-outer membrane complex. The results presented here suggest that the binding between membrane and DNA is specific and involves a membrane protein having a molecular weight of 13,000.
