Prokaryotic cytoskeletons: protein filaments organizing small cells

Abstract: Most, if not all, bacterial and archaeal cells contain at least one protein filament system. Although these filament systems in some cases form structures that are very similar to eukaryotic cytoskeletons, the term 'prokaryotic cytoskeletons' is used to refer to many different kinds of protein filaments. Cytoskeletons achieve their functions through polymerization of protein monomers and the resulting ability to access length scales larger than the size of the monomer. Prokaryotic cytoskeletons are involved in… Show more

“…In these organisms, cell shape and spatial regulation of peptidoglycan synthesis are both tied to the actin homolog MreB (Dominguez-Escobar et al, 2011;Errington 2015;Gitai et al, 2004;Garner et al, 2011;van den Ent, Amos, van Teeffelen et al, 2011). MreB is one of several bacterial proteins that are now widely accepted as components of the bacterial cytoskeleton, which have been reviewed in (Cabeen & Jacobs-Wagner 2010;Carballido-Lopez & Errington 2003;Errington 2015;Eun et al, 2015;Wagstaff & Lowe 2018). MreB is one of several bacterial proteins that are now widely accepted as components of the bacterial cytoskeleton, which have been reviewed in (Cabeen & Jacobs-Wagner 2010;Carballido-Lopez & Errington 2003;Errington 2015;Eun et al, 2015;Wagstaff & Lowe 2018).…”

“…Similar to their eukaryotic homologs, polymerization of bacterial cytoskeletal proteins is important for their roles in cellular functions, including shape maintenance (Carballido-Lopez & Errington 2003;Eun et al, 2015;Wagstaff & Lowe 2018). These proteins also exhibit structural, although not necessarily sequence similarity, to eukaryotic cytoskeleton proteins.…”

“…In Escherichia coli, cell division is executed by a large multi-protein complex known as the divisome. The most well conserved component of the divisome is FtsZ, a prokaryotic homolog of tubulin (Erickson et al, 2010;Wagstaff and Löwe, 2018). Cytoplasmic FtsZ is tethered to the inner membrane by two proteins, the actin homolog FtsA and the transmembrane division protein ZipA (Pichoff and Lutkenhaus, 2002), forming an early divisome structure called the proto-ring.…”

“…Our resultsestablish SAXS as areliable structural analysism ethod for long DNA nanotubes and could assist in the rational design of these structures.Genetically encoded nanotubes made from biomacromolecules, such as cytoskeletal filaments, [1] channeling protein nanotubes, [2] and membrane channels, [3] are critical cellular components. However,l ittle is knowna bout the structures of assembled DNA nanotubes in solution.H ere we report an in situ exploration of segmented DNA nanotubes, composed of multiple units with set length distributions, by using synchrotron small-angle X-ray scattering (SAXS).…”
