The divisome is essential for binary fission in bacteria.
It includes key proteins like FtsZ, which forms a ring at the future site of division.
FtsI and FtsK are other important proteins involved in peptidoglycan synthesis and chromosome segregation, respectively.
The divisome assembles at the mid-cell after DNA replication is nearly complete.
Mutations in divisome components can lead to cell division defects or failure.
