Cytoskeleton in the archaebacterium Thermoplasma acidophilum? Viscosity increase in soluble extracts.

Author information

Biology Department, University of Massachusetts, Amherst.


Thermoplasma acidophilum has no cell wall, and so its irregular shape implies the presence of a cytoskeleton. When soluble extracts of T. acidophilum were incubated in vitro they increased in viscosity, suggestive of a polymerizable component. Optimal conditions for the viscosity increase coincided with physiological ionic concentrations. Electron micrographs of negatively stained extracts showed a meshlike lattice of elements 10 nm in diameter similar to nuclear lamins. However, immunologically there was no cross-reaction with lamins nor with the other eukaryotic cytoskeletal proteins tested: tubulin, calmodulin, giardin, actin or myosin.
