title: [Ribosomal protein S1 in the complex of E. coli ribosomal subunit 30S with phage MS2 RNA interacts with internal region of the replicase gene].
abstract: The MS2 RNA fragments bound to ribosomal protein S1 within the complex of MS2 RNA with 30S ribosomal subunit have been isolated using a specially developed procedure and sequenced by the base-specific enzymatic method. The S1-binding site on MS2 RNA was identified as UUUCUUACAUGACAAAUCCUUGUCAUG and mapped within the replicase gene at positions 2030-2056. This finding suggests that ribosome-MS2 RNA interaction involves at least two different regions of the phage RNA--the internal region of the replicase gene (S1-binding site) and ribosome-binding site of the coat protein gene. The possible spatial proximity between these two regions is discussed.
