  • Essential components for cell viability

    *Japanese only

    Researchers led by Drs. Shigeyuki Yokoyama and Tatsuo Yanagisawa revealed the translation elongation factor P (EF-P) and the Arg residue at position 32 are constituent elements of the cell viability of a human pathogen, Neisseria meningitides.


  • Overall structure of the eukaryotic translation initiation 2B (eIF2B), revealed

    *Japanese only

    eIF2B.png Researchers led by Drs. Shigeyuki Yokoyama and Takuhiro Ito have successfully determined the structure of the eIF2B and unveiled its structural framework for the eIF2B associated mechanism of the pathogenesis of vanishing white matter (VWM) or childhood ataxia with central nervous system hypomyelination (CACH).

 
 
 
  • Structure of RNA Polymerase, revealed

    Structure of RNA Polymerase, revealed Researchers led by Drs. Shigeyuki Yokoyama and Shun-ichi Sekine have shown that the conversion between the tight and ratcheted forms could be the general basis for the regulation of RNAP functions in all cellular multisubunit RNAPs.

 
  • Redox switch in Lon protease, revealed

    Redox switch in Lon protease, revealed Researchers led by Drs. Shigeyuki Yokoyama and Wataru Nishii have discovered that Lon protease is regulated by a redox-dependent disulfide bond that determines the size of its exit pore.



 
  • Structure of alanyl-tRNA synthetase, revealed

    Structure of alanyl-tRNA synthetase, revealed Researchers led by Dr. Shigeyuki Yokoyama have determined the crystal structure of alanyl-tRNA synthetase and elucidated astonishing selective tRNA aminoacylation mechanisms.

 
  • Structure of SelA, the 21st amino acid synthase, revealed

    Structure of SelA, the 21st amino acid synthase, revealed Researchers led by Dr. Shigeyuki Yokoyama have determined the crystal structure of the Sec synthase, SelA, responsible for the Ser-to-Sec conversion in bacteria. They determined the structures of SelA alone and in a complex with tRNASec.
