Septation

General Description

Invagination of the membrane that occurs after replication to separate daughter cells.

Components

FtsZ(Z ring), FtsA, FtsK, FtsN, FtsI, FtsE, FtsX, etc.

In order to ensure the chromosome doesn't get guillotined, TopoIV and the XerCD recombinase are also localized to the septa, via FtsK, but they are not involved directly in the membrane closure.

Regulation

Z ring formation can be inhibited by sulA (recA- dependent SOS response)
