Restoration by Ribosomal Protein S1 of the Defective Translation in a Temperature-sensitive Mutant of Escherichia Coli K-12: Characterization and Genetic Studies
Overview
Affiliations
A temperature-sensitive mutant of Escherichia coli was isolated that had a temperature-sensitive defect in ribosomal-wash protein(s) required for translation in vitro of E. coli endogenous messenger ribonucleic acid. It was found that 30S ribosomal protein S1 rescued the defect in the ribosomal-wash protein(s) of the mutant and that the complete restoration to the wild-type level was attained when 1 mol of protein S1 was added to 1 mol of 70S ribosome. The mutation, tss, causing such a defect was mapped at 21 min and was closely linked to the pyrD locus, the region of which was entirely different from that of the other genes coding for the many ribosomal proteins of E. coli. These results indicate that the gene specified by this mutation is involved in the function of the 30S ribosomal protein S1.
