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

Non-enzymatic translocation in ribosomes
✍ Asatryan, L.S. ;Spirin, A.S. 📂 Article 📅 1975 🏛 Springer 🌐 English ⚖ 359 KB

The capablity of ribosomes of four types of streptomycin-resistant mutants (A1, A2, A40 and A60) for non-enzymatic (EF-G--GTP-independent) translocation was tested. It was found that an A40 type mutation (amino acid replacement in position 87 of the protein S12 polypeptide chain) leads to activation
