WebbAs their name implies, microtubules are small hollow tubes. Polymerized dimers of α-tubulin and β-tubulin, two globular proteins, comprise the microtubule’s walls (Figure 3.20). With a diameter of about 25 nm, microtubules are cytoskeletons’ widest components. 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.

WebbThe cytoskeleton has three different types of protein elements. From narrowest to widest, they are the microfilaments (actin filaments), intermediate filaments, and microtubules. Microfilaments are often associated with myosin. They provide rigidity and shape to the cell and facilitate cellular movements. WebbOf the three types of protein fibers in the cytoskeleton, microfilaments are the narrowest. They have a diameter of about 7 nm and are made up of many linked monomers of a protein called actin, combined in a structure that resembles a double helix.
