DNA-membrane interactions can localize bacterial cell center Academic Article uri icon


  • In actively growing bacterial cells, the DNA exerts stress on the membrane, in addition to the turgor caused by osmotic pressure. This stress is applied through coupled transcription/ translation and insertion of membrane proteins (so-called “transertion” process). In bacillary bacteria, the strength of this interaction varies along cell length with a minimum at its midpoint, and hence can locate the cell's equator for the assembly of the FtsZ-ring.
