Abstract
The previously reported requirement of ribosomal protein S1 for translation of phage RNA is now shown to be related to the involvement of the protein in initiation complex formation. The structure of the messenger RNA appears to be uniquely related to S1 function, since translation and initiation and midly unfolded phage RNA (by modification with formaldehyde) are independent of S1. It is proposed that S1 functions in conjunction with initiation factor IF-3 by recognizing and unfolding elements of the tertiary structure of phage RNA. A model is suggested for S1 function in both initiation of protein synthesis and initiation of phage RNA replication.Keywords
