FtsZ

Definition

FtsZ is a protein in prokaryotic cells that plays a crucial role in cell division. It forms a contractile ring at the future site of the septum, guiding the division process.

5 Must Know Facts For Your Next Test

1. FtsZ is homologous to tubulin, which is involved in eukaryotic cell division.
2. The FtsZ ring assembles at the midcell location to initiate cytokinesis.
3. FtsZ recruits other proteins necessary for cell wall synthesis during division.
4. Mutations in the ftsZ gene can lead to abnormal cell division or growth defects.
5. The dynamic polymerization and depolymerization of FtsZ filaments are essential for its function.
