Mutations at position A960 of E. coli 23 S ribosomal RNA influence the structure of 5 S ribosomal RNA and the peptidyltransferase region of 23 S ribosomal RNA.

Abstract excerpt

The proximity of loop D of 5 S rRNA to two regions of 23 S rRNA, domain II involved in translocation and domain V involved in peptide bond formation, is known from previous cross-linking experiments. Here, we have used site-directed mutagenesis and chemical probing to further define these contacts and possible sites of communication between 5 S and 23 S rRNA. Three different mutants were constructed at position...
