Spiroplasmas belong to the class Mollicutes, representing the minimal, free-living, and self-replicating forms of life. Spiroplasmas are helical wall-less bacteria and the only ones known to swim by means of a linear motor (rather than the near-unive

Amyloid fibrils are ordered polymers in which constituent polypeptides adopt a non-native fold. Despite their importance in degenerative human diseases, the overall structure of amyloid fibrils remains unknown. High-resolution studies of model peptid

Archaea, constituting a third domain of life between Eubacteria and Eukarya, characteristically inhabit extreme environments. They swim by rotating flagellar filaments that are phenomenologically and functionally similar to those of eubacteria. Howev

Splicing of pre-mRNA takes place on a massive macromolecular machine in the nucleus of eukaryotic cells, the supraspliceosome. This particle is a multicomponent biological complex of RNA and proteins. It is composed of four sub-structures termed nati

In prion diseases, the mammalian prion protein PrP is converted from a monomeric, mainly alpha-helical state into beta-rich amyloid fibrils. To examine the structure of the misfolded state, amyloid fibrils were grown from a beta form of recombinant m

Of the two known “complex” flagellar filaments, those of Pseudomonas are far more flexible than those of Rhizobium. Their diameter is larger and their outer three-start ridges and grooves are more prominent. Although the symmetry of both complex

Summary Bacterial flagella, the organelles of motility, are commonly divided into two classes: ‘plain’ and ‘complex’. The complex filaments are pairwise, helically perturbed forms of the plain filaments and have been reported to occur only in

Although the phenomenology and mechanics of swimming are very similar in eubacteria and archaeabacteria (e.g. reversible rotation, helical polymorphism of the filament and formation of bundles), the dynamic flagellar filaments seem completely unrelat

Amyloid fibrils are insoluble aggregates that result from the self-assembly of partially unfolded proteins. Regardless of the native structure of the precursor proteins, the predominant secondary structure in the fibrillar form is β-sheet. Proteins

Common prokaryotic motility modes are swimming by means of rotating internal or external flagellar filaments or gliding by means of retracting pili. The archaeabacterial flagellar filament differs significantly from the eubacterial flagellum: (1) Its
