Required for association of the 30S and 50S subunits to form the 70S ribosome, for tRNA binding and peptide bond formation. It has been suggested to have peptidyltransferase activity; this is somewhat controversial (By similarity). Makes several contacts with the 16S rRNA (forming bridge B7b) in the 70S ribosome.[HAMAP-Rule:MF_01320_B] Publication Abstract from PubMed We report crystal structures of the Thermus thermophilus ribosome at 2.3- to 2.5-A resolution, which have enabled modeling of rRNA modifications. The structures reveal contacts of modified nucleotides with mRNA and tRNAs or protein pY, and contacts within the ribosome interior stabilizing the functional fold of rRNA. Our work provides a resource to explore the roles of rRNA modifications and yields a more comprehensive atomic model of a bacterial ribosome.
