Webbhas a cytoskeleton—a kind of a network of support beams that gives the living cell structural reinforce-ment. A microtubule (Figure 1) is a very stiff poly-mer and it is the main constituent of the cytoskeleton. The monomers in a microtubule are proteins that consist of about 800 amino acids. Two conformational states are possible for each ... WebbThe submembranous cytoskeleton is a network of structural proteins, including ankyrin, fodrin and spectrin, that forms underneath the plasmalemma and interacts directly with integral membrane proteins. The formation of the submembranous cytoskeleton is correlated with the appearance of cell–cell contacts in cultured kidney cells (Fig. 5 ).

WebbA protein called tubulin is responsible for the formation of microtubules, which are the largest type of filament with a diameter of about 25 nanometers (nm). Microtubules are composed of a protein called tubulin. Actin filaments are the smallest type of filament, with a diameter of only about 6 nm and made of a protein called actin. Webb24 feb. 2024 · MreB and FtsA are the actin-like proteins. Other cytoskeletal types in prokaryotes are MinD, Crescentin, ParM and SopA, MinCDE system, Bactofilin, and Crenactin. Although some of the cytoskeletons in eukaryotes are similar in form and structure with those in the prokaryotes, they basically differ in function.
