Characteristic features of the large subunit, shown below in the "Crown View", include the central protuberance (CP) and the two stalks, which are named according to their bacterial protein components (L1 stalk on the left as seen from the subunit interface and L7/L12 on the right). There are three binding sites for tRNA, the A-site, P-site and E-site (see article on protein translation for detai… WebIn the bacterial ribosome, the large subunit is denoted the 50S, the small subunit 30S, and the entire ribosome 70S, according to their rates of sedimentation during ultracentrifugation. The bacterial small subunit consists of the 16S ribosomal (rRNA), which is approximately 1500 nucleotides, and around 20 small proteins (named S1, S2, etc.).

Ribosomes are macromolecular machines, found within all cells, that perform biological protein synthesis (mRNA translation). Ribosomes link amino acids together in the order specified by the codons of messenger RNA (mRNA) molecules to form polypeptide chains. Ribosomes consist of two major components: the small and large ribosomal subunits. Each subunit consists o…
