Ribosome crystal structures have revealed that two small subunit proteins, S9 and S13, have C-terminal tails, which, together with several features of 16S rRNA, contact the anticodon stem-loop of P-site tRNA. To test the functional importance of these protein tails, we created genomic deletions of the C-terminal regions of S9 and S13. All of the tail deletions, including double mutants containing deletions in both S9 and S13, were viable, showing that Escherichia coli cells can synthesize all… CONTINUE READING
