Summary
Ribosomal proteins fromE. coli mutant N421 which is a spontaneous revertant from streptomycin dependence to independence have been compared to those of the wild type by two-dimensional polyacrylamide gel electrophoresis and by four immunochemical methods. The only detectable difference is a change in protein S5. This finding suggests that reversion from streptomycin dependence to independence can be caused not only by a mutation in protein S4, as described earlier, but also in protein S5.
