Abstract

X-ray diffraction patterns showing 9 maxima at spacings greater than 10 Å have been obtained from concentrated gels of E. coli 50 s ribosomes. The observed spacings can be fitted to integral orders of 212 Å basic repeat, with the exception of a reflection at 45·5 Å. It is suggested that both the 50 s and 70 s particles form a linear polymer in the concentrated gel with a repeat spacing of 212 Å. The 45·5 Å reflection is believed to arise from some internal structure in the ribosome.
