A Gallery of Ribosome Microcrystals

Ribosome crystals that are large enough for X-ray diffraction studies have been obtained, so far, only from bacteria. In eukaryotes ribosome microcrystals have been discovered first within the cell and then also in cell-derived systems such as homogenates and cell extracts. This last result was announced in 1979 in the Journal of Supramolecular Structure (Vol. 10. pp. 349-357), but only a few electron micrographs were printed on that occasion, so it may be useful to provide other pictures of that discovery. The present “Gallery” has precisely such a purpose and represents therefore a memory bank of structures that remain to this day the best example of eukaryotic ribosome microcrystals.
