Ribosomal protein structures: insights into the architecture, machinery and evolution of the ribosome.
Models of the bacterial ribosome based on recent structural analyses are beginning to provide new insights into the protein synthetic machinery. Central to evolving models are the high-resolution structures of individual ribosomal proteins, which represent detailed probes of their local RNA and protein environments. Ribosomal proteins are extremely ancient molecules; the structures therefore also provide a unique window into early protein evolution. Many of the proteins contain domains that are present in more recently evolved families of RNA- and DNA-binding proteins. Such structural homology can be used to predict mechanisms by which proteins interact with RNA in the ribosome.
