title: The binding site for ribosomal protein L11 within 23 S ribosomal RNA of Escherichia coli.
abstract: Ribosomal protein L11 of Escherichia coli was bound to 23 S rRNA and the resultant complex was digested with ribonuclease T1. A single RNA fragment, protected by protein L11, was isolated from such digests and was shown to rebind specifically to protein L11. The nucleotide sequence of this RNA fragment was examined by two-dimensional fingerprinting of ribonuclease digests. It proved to be 61 residues long and the constituent oligonucleotides could be fitted perfectly between residues 1052 and 1112 of the nucleotide sequence of E. coli 23 S rRNA.
