The ribosome is a ribonucleoprotein complex which performs the crucial function of protein biosynthesis. Its role is to decode mRNAs within the cell and to synthesize the corresponding proteins. Ribosomal protein S7 is located at the head of the small (30S) subunit of the ribosome and faces into the decoding centre. S7 is one of the primary 16S rRNA-binding proteins responsible for initiating the assembly of the head of the 30S subunit. In addition, S7 has been shown to be the major protein component to cross-link with tRNA molecules bound at both the aminoacyl-tRNA (A) and peptidyl-tRNA (P) sites of the ribosome. The ribosomal protein S7 clearly plays an important role in ribosome function. It was hoped that an atomic-resolution structure of this protein would aid our understanding of ribosomal mechanisms.
