Some x-ray diffraction patterns from single crystals of the large ribosomal subunit from Bacillus stearothermophilus

X-ray diffraction patterns of three-dimensional crystals of the large ribosomal subunit from Bacillus stearothermophilus have been obtained using a synchrotron radiation beam. The patterns contain resolved diffraction spots and indicate packing in relatively small unit cells, the dimensions of which have been tentatively determined. The internal order of the crystals, as reflected in these patterns, has been correlated with the size, shape and conditions of growth of these crystals.
