Mutants resistant to (Str-R) or dependent on streptomycin (Str-D) were isolated from several streptomycin independent (Str-I) strains of Escherichia coli. From 90 of these mutants ribosomes were isolated and the ribosomal proteins analyzed by two-dimensional polyacrylamide gel electrophoresis. The r
Streptomycin-resistant and dependent mutants were isolated from Bacillus subtilis ATCC 6633. Ribosomal proteins were analysed from six such mutants with chromatography on carboxymethyl cellulose or phosphocellulose columns. An altered specific 30s ribosomal protein, 30B, could be detected in all of
