Nitrogen source and the retrograde signalling pathway affect detection, not generation, of the [URE3] prionHerman K Edskes
Laboratory of Biochemistry and Genetics, National Institute of Diabetes, Digestive and Kidney Diseases, National Institutes of Health, Bethesda, MD 20892-0830, USA
Yeast 23:833-40. 2006..Moreover, the presence of both ammonia and glutamate blocks USA uptake in a known [URE3] strain, so that detection of the prion is prevented, rather than its generation...

The structural basis of recognition and removal of cellular mRNA 7-methyl G 'caps' by a viral capsid protein: a unique viral response to host defenseJinghua Tang
Department of Molecular Biology, The Scripps Research Institute, 10550 North Torrey Pines Road, La Jolla, CA 92037, USA
J Mol Recognit 18:158-68. 2005..Along with His154, the reaction requires a cluster of positive charge adjoining the trench and residues Tyr 452, Tyr150 and either Tyr or Phe at position 538. A tentative mechanism for decapping is proposed...
Interactions among prions and prion "strains" in yeastMichael E Bradley
Laboratory for Molecular Biology, Department of Biological Sciences, University of Illinois, 900 South Ashland Avenue, Chicago 60607, USA
Proc Natl Acad Sci U S A 99:16392-9. 2002..These results reinforce earlier reports that heterologous prions interact, but suggest that such interactions can not only positively, but also negatively, influence the de novo generation of prions...
L-A virus at 3.4 A resolution reveals particle architecture and mRNA decapping mechanismHisashi Naitow
Department of Molecular Biology, The Scripps Research Institute, 10550 North Torrey Pines Road, La Jolla, California 92037, USA
Nat Struct Biol 9:725-8. 2002..The L-A virus decaps cellular mRNA to efficiently translate its own uncapped mRNA. Our structure reveals a trench at the active site of the decapping reaction and suggests a role for nearby residues in the reaction...
