The accessibility of each of the proteins on the 50S ribosomal subunit of Escherichia coli was investigated by establishing whether immunoglobulins (IgG), specific for each of the 34 proteins from the 50S subunit, were able to bind to the 50S subunit. The main criterion for accessibility was the for
Bacterial ribosomes consist of two subunits, the larger 50S and the smaller 30S. Both subunits have a protein to RNA ratio of about 1:2. The larger subunit contains 23S RNA of mol.wt. 1.1 x 106 and the smaller subunit contains 16S RNA of mol.wt. 0.55 X 10 6. The proteins of ribosomes are very comple
