Ribosome structures from various species are known at the atomic level, but obtaining the structure of the human ribosome has ...Ribosomes are translational machineries that catalyse protein synthesis. Ribosome structures from various species are known at the atomic level, but obtaining the structure of the human ribosome has remained a challenge; efforts to address this would be highly relevant with regard to human diseases. Here we report the near-atomic structure of the human ribosome derived from high-resolution single-particle cryo-electron microscopy and atomic model building. The structure has an average resolution of 3.6 Å, reaching 2.9 Å resolution in the most stable regions. It provides unprecedented insights into ribosomal RNA entities and amino acid side chains, notably of the transfer RNA binding sites and specific molecular interactions with the exit site tRNA. It reveals atomic details of the subunit interface, which is seen to remodel strongly upon rotational movements of the ribosomal subunits. Furthermore, the structure paves the way for analysing antibiotic side effects and diseases associated with deregulated protein synthesis.

2019年1月31日: EMDBのIDの桁数の変更

EMDBのIDの桁数の変更

  • EMDBエントリに付与されているアクセスコード(EMDB-ID)は4桁の数字(例、EMD-1234)でしたが、間もなく枯渇します。これまでの4桁のID番号は4桁のまま変更されませんが、4桁の数字を使い切った後に発行されるIDは5桁以上の数字(例、EMD-12345)になります。5桁のIDは2019年の春頃から発行される見通しです。
  • EM Navigator/万見では、接頭語「EMD-」は省略されています。
