摘要：With a stepwise degradation and terminal labeling procedure the 3'-terminal sequence of E. coli 16S ribosomal RNA is shown to be Pyd-A-C-C-U-C-C-U-U-AOH. It is suggested that this region of the RNA is able to interact with mRNA and that the 3'-terminal U-U-AOH is involved in the termination of protein synthesis through base-pairing with terminator codons. The sequence A-C-C-U-C-C could recognize a conserved sequence found in the ribosome binding sites of various coliphage mRNAs; it may thus be involved in the formation of the mRNA{middle dot}30S subunit complex.
