Figure 2. The domain structure of FtsZ.

Figure 2

The domain structure applies to most FtsZ proteins. The N terminus and variable spacer domains are highly variable in length, and their precise functions are unknown. The core region displays most similarity to tubulin and is required for GTP binding and hydrolysis as well as assembly into protofilaments. The C-terminal peptide interacts with other cell-division proteins recruited by FtsZ such as ZipA, FtsA and FtsW, and might function mainly to anchor the Z ring to the membrane using these proteins.
