Subsystem: Bacterial Cytoskeleton
This subsystem's description is:
The cytoskeletal structures play important roles in cell division, cell polarity, cell shape regulation, plasmid partition.
Prokaryotic cells contain homologs for each of the three major groups of eukaryotic cytoskeletal proteins, i.e.,
intermediate filament proteins.
In addition, they have a fourth group, the MinD-ParA group, that appears to be unique to bacteria.
The three-dimensional structures of the eukaryotic and prokaryotic actin and tubulin homologs are generally quite similar despite relatively modest sequence homology in many cases.
Eukaryotic and prokaryotic cytoskeletal proteins also share two important properties:
First, they self-assemble into filamentous polymers in vitro in the presence of ATP (for most of the proteins) or GTP (for tubulin and tubulin homologs).
Second, they are organized into ordered long-range structures within the cell.
