Journal: Nat Struct Mol Biol / Year: 2019 Title: Structure of the 80S ribosome-Xrn1 nuclease complex. Authors: Petr Tesina / Elisabeth Heckel / Jingdong Cheng / Micheline Fromont-Racine / Robert Buschauer / Lukas Kater / Birgitta Beatrix / Otto Berninghausen / Alain Jacquier / Thomas Becker / Roland Beckmann / Abstract: Messenger RNA (mRNA) homeostasis represents an essential part of gene expression, in which the generation of mRNA by RNA polymerase is counter-balanced by its degradation by nucleases. The conserved ...Messenger RNA (mRNA) homeostasis represents an essential part of gene expression, in which the generation of mRNA by RNA polymerase is counter-balanced by its degradation by nucleases. The conserved 5'-to-3' exoribonuclease Xrn1 has a crucial role in eukaryotic mRNA homeostasis by degrading decapped or cleaved mRNAs post-translationally and, more surprisingly, also co-translationally. Here we report that active Xrn1 can directly and specifically interact with the translation machinery. A cryo-electron microscopy structure of a programmed Saccharomyces cerevisiae 80S ribosome-Xrn1 nuclease complex reveals how the conserved core of Xrn1 enables binding at the mRNA exit site of the ribosome. This interface provides a conduit for channelling of the mRNA from the ribosomal decoding site directly into the active center of the nuclease, thus separating mRNA decoding from degradation by only 17 ± 1 nucleotides. These findings explain how rapid 5'-to-3' mRNA degradation is coupled efficiently to its final round of mRNA translation.

In the structure databanks used in Yorodumi, some data are registered as the other names, "COVID-19 virus" and "2019-nCoV". Here are the details of the virus and the list of structure data.

EMDB accession codes are about to change! (news from PDBe EMDB page)
The allocation of 4 digits for EMDB accession codes will soon come to an end. Whilst these codes will remain in use, new EMDB accession codes will include an additional digit and will expand incrementally as the available range of codes is exhausted. The current 4-digit format prefixed with “EMD-” (i.e. EMD-XXXX) will advance to a 5-digit format (i.e. EMD-XXXXX), and so on. It is currently estimated that the 4-digit codes will be depleted around Spring 2019, at which point the 5-digit format will come into force.
The EM Navigator/Yorodumi systems omit the EMD- prefix.

Yorodumi is a browser for structure data from EMDB, PDB, SASBDB, etc.
This page is also the successor to EM Navigator detail page, and also detail information page/front-end page for Omokage search.
The word "yorodu" (or yorozu) is an old Japanese word meaning "ten thousand". "mi" (miru) is to see.
