The gene ftsZ plays a central role in division.

Mutations in ftsZ block septum formation and generate filaments.

Overexpression induces minicells by causing an increased number of septation events per unit cell mass.

FtsZ (the protein) recruits a battery of cell division proteins that are responsible for synthesis of the new septum.
