title: Two-dimensional crystalline sheets of Bacillus stearothermophilus 50S ribosomal particles.
abstract: Two-dimensional crystalline sheets of the large ribosomal subunit from Bacillus stearothermophilus have been obtained using a slightly modified procedure to that for growing three-dimensional crystals of the same material. The crystalline subunits are packed within monolayers in a relatively small unit cell, the dimensions of which are closely related to those observed for two forms of the three-dimensional crystals. The packing symmetry is p121, and the optical diffraction patterns of micrographs of negatively stained crystals extend to approximately 3.0 nm.
