title: A 5 S rRNA-like secondary structure in the 7 SL RNA may define a ribosomal binding site of the signal recognition particle.
abstract: A new secondary structure model for parts of the 7 SL RNA is proposed which indicates for a stretch of at least 40 bases a strong structural homology to the ribosomal protein L5 binding site of eukaryotic 5 S rRNA. It is suggested that the 5 S rRNA-like structural part of 7 SL RNA mediates binding of the signal recognition particle near to the peptidyl transferase center of the ribosome.
