Crystal structure of the eukaryotic ribosome
WebWe have determined the crystal structure of the Tetrahymena thermophila 40S ribosomal subunit in complex with eukaryotic initiation factor 1 (eIF1) at a resolution of 3.9 angstroms. The structure reveals the fold of the entire 18S ribosomal RNA and of all ribosomal proteins of the 40S subunit, and defines the interactions with eIF1. WebJan 1, 2013 · Ribosomes are biological assemblies consisting of more than 50 different proteins and several thousands of RNA bases. Recently the structure of the eukaryotic 80S ribosome was determined by methods of X-ray crystallography. This chapter highlights several steps and...
