Electron image analysis of ribosomal subunits from Thermus aquaticus.

Electron micrographs of ribosomal subunits from the thermophilic bacterium Thermus aquaticus were analysed using multivariate statistical analysis and characteristic views constructed to reproducible spatial resolutions ranging from 1.9 to 3.6 nm. These views were comparable to morphological classes of Escherichia coli ribosomal subunits, albeit with differences in fine features also found in archaebacterial ribosomes.
